Wire transfers are very difficult to reverse in most cases. That is the reason that many payees insist on wire transfers for payment of large sums. Once the money is in the target account, there are few reasons that a bank can reverse it (unlike credit or debit transactions). For this reason, wire senders are always encouraged to double check the information before submitting a transfer.
Wire transfers are governed by the Uniform Commercial Code, section 4A. There is a section (4A-207) that deals directly with the misdescription of the beneficiary. Unfortunately for you, that section allows a bank to complete the transfer solely by the account number unless it has positive knowledge that the name and account number refer to different persons. Here's the exact language :
"if the beneficiary's bank does not know that the name and number refer to different persons, it may rely on the number as the proper identification of the beneficiary of the order. The beneficiary's bank need not determine whether the name and number refer to the same person."
Basically, that means that you can't go after the receiving bank (Wachovia) for not verifying that the name did not match the account. Under the rules, it appears that the only recourse you have is to go after the person who mistakenly received your money. I imagine that this would probably involve a lawyer in order to get Wachovia to hand over the identity of the account holder.
