Look, I'm gonna say only one thing. Having dealt with transactions internationally for several years now, legitimately and for fake watches.
You have to understand, no TD is going to EVER email and or call a bank for a transaction for an ILLEGAL \WATCH.
If you ever talked to banking support, regarding transaction, lost funds, etc, they'll ask why this transaction happened, what it's for, why is he receiving it, etc, why it needs a refund right? It's not as easy as you think.
If this was for a legitimate transfer, or remittance, or anything legal, then this is easy. Proof of payment, proof of services exchanged, legitimate source of money, company papers, all are legal and can be provided. But illegal watch? There's none of that. "Oh yes I received this remittance from a friend...." is not an excuse that will fly in international banking.
It's not that simple. They risk their lives, going to jail, fraud, illegal wire transfers. For you it's money, yes, this sucks, I'm sure the money is floating around somewhere. But into perspective for them, they risk going to 5-10 years in jail for selling counterfeit goods and illegal wire transfers for illegal goods.
And, I don't want to pin the blame on you, because, I understand how frustrating this is. But your accusatory tone and demanding is not going to really help any further. But you sent the money to a wrong name...... this whole thing could have been prevented if you double checked the first time.
Sometimes in the fake watch game, you have to accept loss. My rule is never send money into fake watches, you cannot lose. The TDs here will try their best to service you, but reminder that this is ILLEGAL. Sometimes things will go wrong and you have to accept it.
