How to Handle Customer Complaints in English: Phrases and Examples
Listen carefully, acknowledge the problem and explain a useful next step. Build the English you need for a calm customer conversation or a clear written reply.
A customer says their order arrived late, an item is missing or a promised update never came. You want to help, but finding the right English under pressure can be difficult. A vague apology may leave the customer unsure what will happen next.
A useful response shows that you understand the issue and explains what you can do. This guide gives you a four-step structure, twelve phrases and examples for a conversation and an email. Adapt the details to your role and the options your workplace can offer.
Listen → acknowledge → clarify → act. Let the customer explain, recognise the specific problem, check any missing facts, then describe a next step with an owner and a realistic update time.
Start with a clear response structure
You do not need a long speech. A short response can be helpful if it addresses the actual complaint. Keep your tone calm, use ordinary words and give the customer space to answer your questions.
1. Listen to the whole issue
“Please tell me what happened.”
Let the customer finish before deciding what the problem is.
2. Acknowledge the specific problem
“I'm sorry your order arrived without the lamp.”
Name the issue so the customer knows you understood it.
3. Check the facts you need
“Could you confirm which item is missing?”
Ask focused questions rather than making the customer repeat everything.
4. Explain the next action
“I'll check the packing record and update you by 2 p.m. today.”
State what you will do and when the customer will hear from you.
If you are replying in writing, summarise the problem first. If you are speaking, a brief check such as “So the box arrived, but the lamp was missing - is that right?” can help you confirm your understanding.
Useful phrases for acknowledging a complaint
Be specific and natural. Thanking someone for reporting an issue can work well, but avoid an enthusiastic tone when they are describing a serious inconvenience.
1. “Thank you for letting us know.”
Recognise that the customer has brought the issue to your attention. Follow it with a response to the problem.
2. “I'm sorry about the delay.”
Apologise for a known problem. Replace delay with the relevant issue, such as the missing item.
3. “I understand why this is frustrating.”
Acknowledge the impact when the customer has expressed frustration. Avoid assuming a feeling they have not described.
4. “Let me make sure I've understood.”
Introduce a short summary of the facts, then ask the customer to confirm or correct it.
“I'm sorry you feel that way” can sound as though the customer's feelings are the problem. Where you know what went wrong, name it directly: “I'm sorry we sent the wrong item.” If you still need to investigate, acknowledge the experience without inventing a cause: “I'm sorry the item was not in the box. I'll check what happened.”
Useful phrases for clarifying and checking
Explain why you need information and use your workplace's usual support channel. For language practice, use imaginary order details. Your aim is to ask only what helps you understand or resolve the complaint.
5. “Could you confirm…?”
Ask for a relevant detail: “Could you confirm the date the parcel arrived?”
6. “When did you first notice the problem?”
Establish the timing without suggesting that the customer caused the issue.
7. “I'll check that for you.”
Use this when you can take the action. Add what you will check if it helps: “I'll check the delivery record for you.”
8. “May I put you on hold while I check?”
On a phone call, ask before putting the customer on hold. If the check will take longer, offer a realistic callback or update.
Try one question at a time in a conversation. In an email, group the details you need into a short, clear request. Avoid asking for information the customer has already provided.
Useful phrases for a solution or next step
Distinguish what is confirmed from what still needs checking. A clear update time can be useful even when you cannot yet give a final resolution time.
9. “Here's what I can do.”
Introduce an available action: “I can check the missing item with our dispatch team.”
10. “Would you prefer… or…?”
Offer a choice only when both options are available: “Would you prefer collection or delivery for the replacement?”
11. “I'll update you by…”
Give a specific time: “I'll update you by 2 p.m. today, South African time.” Choose a commitment you can meet.
12. “I'll refer this to… and…”
Explain a handover: “I'll refer this to our support lead and send you an update tomorrow morning.”
If a replacement, refund or other action needs approval, explain that step before promising the outcome. “I'll ask our support lead to review the replacement request” describes an action you can take. Once the decision is confirmed, tell the customer exactly what has been agreed.
A short customer-service conversation
Customer: “The parcel arrived yesterday, but the lamp was missing. I've already waited a week.”
You: “I'm sorry the lamp was not in the box. I understand why this is frustrating. Let me make sure I've understood: the parcel arrived, but one item was missing?”
Customer: “Yes. The shade was there, but the lamp wasn't.”
You: “Thank you for clarifying. I'll check the packing record with our dispatch team. I'll update you by 2 p.m. today, even if we're still checking the details.”
Customer: “Will you send a replacement?”
You: “I need to confirm that with the team first. I'll include the available options in the update.”
The response confirms the issue, explains an action and sets an update time. It also answers the replacement question honestly. For more help describing progress while a case is being checked, see our project-update guide.
A clear complaint-response email
Subject: Your missing lamp - update by 2 p.m. today
Hi Sam,
Thank you for letting us know that the lamp was missing from your parcel. I'm sorry about the inconvenience.
I'm checking the packing record with our dispatch team. I'll send you an update by 2 p.m. today, South African time, with the next steps or the details we still need to confirm.
You can reply to this email if there is anything else about the delivery we should know.
Kind regards,
Alex
The subject and message give the same commitment. If the investigation is still open at 2 p.m., send the promised update anyway: explain what you checked, what remains unclear and when the customer will hear from you again. Our professional-email guide covers greetings, requests and sign-offs.
When you cannot offer the requested solution
Explain the relevant limit in plain language, then describe any available next step. For example: “I can't confirm a same-day replacement, but I can check the earliest delivery date and call you by noon.” Keep the explanation specific to the situation.
If another person needs to decide, give a useful handover: “Our support lead needs to review this request. I'll pass on the details you've already given us and confirm when you can expect a response.” Avoid sending the customer from person to person without explaining who will act next.
Keep your voice calm when a conversation becomes tense. “I want to help resolve the issue. Could we go through the details one at a time?” can help you return to the facts. Follow your workplace's process if the conversation needs a supervisor.
Common wording mistakes
- “I apologise about the delay.” A natural pattern is “I apologise for the delay” or “I'm sorry about the delay.”
- “Explain me the problem.” Say “Could you explain the problem to me?” Better still, ask about the specific detail you need.
- “I will revert you tomorrow.” For a clear reply across international teams, say “I'll get back to you tomorrow” or “I'll update you tomorrow.”
- “We will sort it out soon.” Add the next action and an update time so the customer knows what to expect.
- “You must have ordered the wrong item.” Check the records before drawing a conclusion: “Let's check the item listed on the order.”
Replies that make the next step clear
Acknowledge the actual problem
I'm sorry about the delay with your order names the issue. Could you explain the problem to me? places to me after the thing being explained.
Promise an action you control
I'll check the packing record and update you by 2 p.m. today gives a concrete action and time without guessing the final outcome.
Explain a review honestly
I'll ask our support lead to review the replacement request and confirm the available options distinguishes a request for review from a promised replacement.
Practise a complete response
Choose one realistic complaint
Use an imaginary missing item, late delivery or unanswered message. Note what the customer knows and what you still need to check.
Say a short reply aloud
Acknowledge the issue, ask one useful question and state your next action. Record yourself if helpful and check that the update time is easy to hear.
Write the follow-up message
Keep the same facts and commitments. Add a clear subject line, then check that you have promised only actions you can take.
Keep the response accurate and proportionate
Acknowledgement before an investigation
You can acknowledge the reported experience without guessing its cause. “I'm sorry the item was missing from the parcel. I'll check the packing record” recognises the problem and explains how you will investigate.
A clear next step while a solution is pending
Explain the next action and give a realistic update time. Say what is confirmed and what still needs checking. Keep the customer informed even when a final answer is not ready.
Straightforward language for support
Match your workplace and customer. Clear, respectful wording is useful in both formal emails and everyday conversations. Avoid jargon that makes the action or timing harder to understand.
Practise helpful customer-service English
Build workplace communication in Business English, then save useful complaint-response phrases with your own examples.
