Dear
You deserve an explanation for what went wrong in our
accounting department, and I hope that this letter will
serve to resolve our recent difficulties.
I know that you can appreciate the fact that it has
taken some time to find out exactly what occurred, and,
therefore, please accept our apologies for error in
this response.
I know how exasperating this has been for you and I am
deeply sorry that it has taken so long to straighten out
this problem. While there is a procedure within our firm
to preclude this type of error from occurring, we are
reinforcing this procedure.
You have been a valued customer of ours for a long time
and we appreciate your affording us the opportunity to serve
you. You may rest assured that this problem will not
surface again.
