[PNC] Implement better tracking for wire transfers

I really need some help / advice because this entire situation has been driving me insane and I am being thrown around in constantly circles by both banks. I am a PNC customer. Here is the story: \- I am a US Citizen planning an international wedding in Oman \- I sent my wedding planner a $12.5K wire payment for services / decor in January \- The receiving bank (National Bank of Oman) received the funds but refused to release them because my wire transfer had a missing IBAN number.. there was literally no input box for me to enter one, but whatever. \- They claimed they sent the wire back and provided paperwork and it’s been two whole months now and still nothing My bank (PNC) is not helpful whatsoever, claiming that the funds are still showing at the receiving bank. The receiving bank (NBO) keeps providing the same document over and over showing the funds were sent back with a UETR code and saying we did our part and sent it back. Both banks are pointing fingers at each other. I shared the document from NBO with my bank and they keep telling me the funds are still at the receiving bank. Neither parties are doing anything to chase up the intermediary / corresponding banks to see where the money is stuck. I’ve opened a formal complaint / case on my bank through CFPB because they were doing absolutely nothing to help me track this down. Even after the case has opened they are telling me the same thing over and over, “we don’t see the money and it’s still showing at the receiving bank”. I asked PNC for a formal wire trace and still, it’s the same information being repeated to me over and over and they will give me 0 other information to help me resolve this. I’ve tried also going back to the person I originally sent the money to get a formal trace on the wire from his bank and they are also giving me the same repeated BS about how they sent it back and give me the same document as before. I am literally desperate and neither banks are willing to help or claim responsibility. I suspect it’s stuck at the intermediary banks (Wells Fargo or Bank of America) but neither are responding to PNC’s recall notice. And I can’t reach out to them myself. My bank is refusing to do so and so is the national bank of oman. Am I out of this money for good? What should I do?
