Dear PAUL SMITH,
We appreciate that you sent us a check for your May bill so quickly. It is regrettable, however, as it seems that you forgot to fill out all the fields on the check. We have sent it back so that you can complete it.
We hope that you can send it back to us soon so that your account won’t incur any late penalties. Thank you.
Sincerely,
Ashrita
