The IRS functionary may be confusing roles in his/her statement. While it is true that IRS rules require that the account to receive a direct deposit tax refund payment belong to the taxpayer, the IRS does not send any form of prenote for these payments. For the IRS to expect that the receiving depository will verify the live payment for name/SSN agreement with account records is unreasonable.
Of course, your bank is going to do everything it can to resolve the situation, but the simple fact is that the IRS should be (and probably is) taking its ruler to the knuckles of the accountant, and not those of the bank.
