Tax Submission

While it isn't currently my primary business, I did prepare taxes fro a couple of clients this year for a fee. We received back a letter from the IRS listing penalties and interest for not filing and paying on time despite the fact that my client did so via certified mail return receipt requested. We submitted the paperwork with proof of mailing, etc. We just got another letter showing the same penalties and more interest, so my client called the IRS. He was told that it didn't matter that he had proof f mailing, that he was still going to be hit for penalties and interest, based on the fact that the IRS cashed the check two months late, so they "must have received it late". I have never heard this before. Have any of you had to deal with such presumptuousness?
