Answer:
If your wire system does "straight-through" processing or you were otherwise not aware of the facts as you describe them until after crediting the account identified by number in the wire instructions, your payment is acceptance of the wire transfer, you are entitled to payment by the originator's bank, and payment is final.
If, on the other hand, your procedure is to examine wire transfer instructions to verify payee information against your account information, and you become aware of the discrepancy you've described, you should refuse the transfer due to the account ownership/payee mismatch.
See UCC 4A-207(b) for details.
