Dear Mrs. Hugo:

Good day!

I would like to apologize for the inconvenience made by our accountant.  Due to her tons of workload, she was not able to double check the bill that was sent to you last September 5. This bill is not correct; you have charge an extra Php585.

In this regard, we will correct it by crediting this amount to your account. If you have any clarification regarding this matter, just call me anytime.

Once again, please accept our sincere apology.

Sincerely yours,

Malou L. Cabrera
