Dear Mrs Charles

Thank you for your telephone call of 20 April.

I understand that you received an invoice from us, dated 19 April, which quoted an incorrect bill amount.

I have investigated the matter with our Accounts department who were responsible for sending out the invoice. It appears that a member of staff typed the wrong number by mistake.

I apologise for this and the inconvenience it has caused. I agree that on this occasion our service has not been to the high standards we aim to achieve.

As a result of your complaint, our Accounts manager is reviewing staff training to ensure that this does not happen again.

Thank you again, Mr Charles, for bringing this to my attention. I hope this letter has resolved your concerns, but if you need any more information please contact me on my direct line 01234 130989.

Yours sincerely

Caroline Ashworth

Customer Service Manager
