Format for Apology Email for Unhelpful Customer Representative Service
Dear Ms. Ana,
On behalf of my company, I would like to sincerely apologize for the unpleasant experience you had while having a telephonic conversation with one of our customer care representatives. I completely understand that it was not right on his behalf to not give a satisfactory solution to your problem.
We are aware that you made that call for the service of your laptop that you had bought with us but there were certain issues related with the bill that proves the warranty of the product. We regret the inconvenience caused to you and we have taken all the necessary measures to condemn the actions of our executive as the company believes in offering the best of the services to our customers. We completely take the responsibility of this misconduct and we are hopeful that you will continue to place your trust in us.
I personally have gone through the issue that you have been witnessing and have arranged for a doorstep delivery service for you to take care of your laptop. As an apology compensation, this service will not be chargeable.
