Sometimes we as customers don’t like what we’ve purchased, and we have an obligation to complain. Unfortunately, some business don’t feel that they have an obligation to respond, and they act like once the sale closes, the customer disappears. I’m writing to thank you for not being one of those companies.
Your response to my dissatisfaction with <object of complaint> was prompt, understanding and thoroughly professional. <description of action>.
Despite my previous dissatisfaction, I will continue to be a customer of <company name>. Your actions have seen to that. Thank you very much for your courtesy and service.
