Complain About Poor Service or a Faulty Product | Letter-Writing Guide


Omit irrelevant details and use firm but respectful language. Communicate facts more than emotions. If this letter does not bring action, assume a stronger but still credible tone in the next one. Send only photocopies of receipts and other documents, and retain all original records.


1. Tell why it is important that the reader take care of the complaint. Give a full description of your complaint, including relevant dates, verbal exchanges, complete names, actions, amounts, invoice numbers, or previous correspondence.

  • It has been over thirty days since I placed an order for new tires, but I have not received confirmation of a shipping date. It is important that I know the status of my order, so I can plan for servicing my fleet.
  • I regret that I must write about the way your receptionist treated my assistant when he delivered the contracts. As he attempted to hand the receptionist the bundle, she said, "Hold your horses sweetie; you're not the only one in this room!" When my assistant attempted to explain what he was doing, she said, "I don't care if you're King of England! I'm busy!" A good working relationship is placed in jeopardy by such unprofessional behavior.
  • I am very dissatisfied with the performance of my newly assigned caseworker. It was my understanding that we would meet weekly to review my progress, but I have only seen him once in the last five weeks.
  • I was surprised when my son returned home and informed me that you had charged him the full amount for his new rifle after you had assured me that he would receive a 10% discount.
  • I regret that I must call your attention to the faulty workmanship on the hinges of the chest I purchased last week at your showroom outlet. The enclosed documents show that the warranty on the chest covers faulty workmanship and materials.
    Since the warranty is good for only one week following the purchase, I am also enclosing a copy of the receipt dated May 25, just three days ago.
  • Even though you assured me that you would send a refund by June 1, I have not received it. I have now purchased another model and need the money immediately to cover the payment. I feel that I am entitled to a full refund plus the interest that has accrued on my credit card.
  • We have always enjoyed our association with your firm, so we were shocked at the callous treatment we received from your sales representative last Thursday. During our negotiations she used extremely offensive language. Her behavior places our working relationship with your firm at risk.
  • I know that you strive for customer satisfaction, so I think you should know about the rude behavior your new employee exhibited last Saturday. When we asked whether we could exchange some merchandise, he said he didn't know, and walked away. My wife thought there had been a misunderstanding, so she approached him again with the same question. He repeated the same words with a smirk and walked away again. It was not the kind of service we have come to expect from your company.
  • After several attempts to resolve this problem by phone, I am writing to get my account straightened out. I am enclosing copies of cancelled checks that verify every payment I made in September.
  • We are having continual problems with the dishwasher we bought from you on November 15. Currently, the dry cycle does not work. It is difficult for us to fulfill our obligations when the equipment we count on does not function.
  • In your last letter you stated that you would notify us by September 15 whether we could move into the apartment on October 1. It is now September 24, and we need to know immediately.
  • I am writing to inform you that the cabinet I purchased on May 5, was delivered with a deep scratch on the door.
  • I notice from my last credit card statement that you have billed me twice for the same purchase of June 30.

2. State what you expect as a reasonable response. Be firm about any agreed-upon prices, deadlines, guarantees, or services (include copies of such agreements). Assume that your reader will be fair and will take appropriate action, until he or she proves otherwise.

  • I suspect that this comes to you as a surprise, and that you will surely take measures to assure that customers are treated with more courtesy in the future. This employee is not serving the best interests of your store by having such an evasive and unresponsive attitude.
  • Since the warranty is still in force, would you please either send a service representative to correct the problem or provide us with a new machine. I am trusting in your advertising that promises service within 24 hours.
  • You will recall that we were considering the Doe model. Because you had made a special purchase, you were willing to sell it at a discount.
  • I trust that you will let me know immediately so we can make other plans if necessary.
  • I want to return the washer for the full refund your company guarantees. You may pick it up any weekday from 1:00 to 5:00 p.m. Please call to confirm a time.
  • Please have your delivery crew pick it up and exchange it for one that is not damaged. They may call during work hours any day except Saturday.

3. Close with an expression of confidence or anticipation.

  • Since the agreed-upon price was $297.00, I trust that there was a clerical error and that you will refund him the difference. Please send him a check or credit his account with that amount, since he plans to make other purchases.
  • We have relied on your service for the past five years, and we trust that this relationship can continue.
  • I felt that if I brought this problem to your personal attention you would see that it was resolved.
  • I hope we can regain the confidence that we once had in your product.
  • You have been so responsive to our needs in the past that I am confident you will handle this case well.

  • I believe this problem must be distressing to you, too, and I trust you will notify us by June 1 what action has been taken.
  • Unless we receive a suitable response by October 15, we will cancel our account with your firm.
  • If you do not respond by August 15, we will refer the matter to our legal counsel.
  • I will refer this matter to the Environmental Protection Agency unless you take appropriate action by July 3.
  • I trust that you can resolve this problem without my having to refer it to the company president.
