I am writing to discuss the carpet cleaning services that our company, A and D Carpet Cleaning, provided at your house on Thursday, February 25th. I understand that you are not pleased with the service we provided at that appointment, and I want to express our sincere apology. We strive to meet or exceed our customers’ expectations, and I regret that you were not pleased.

Again, please accept our apology for the level of service that you received. I look forward to hearing from you and to resolving this situation to your satisfaction.
