Re: Check Number [N] for $[N] from your company Dear [Contact Name], Unfortunately, we are unable to accept your recent payment due to insufficient funds as reported by your bank. In order for your account to remain in good standing with our firm, we ask that you send a cashier’s check or money order in the proper amount within the next three days. If the bank is responsible for this error, please notify us with proof from the bank. In this case, we will accept a replacement check from the same account. Please handle this issue without delay, for prolonging the matter may affect your account with us. If you have questions or concerns, please call me, and I would be happy to go over the situation with you.
