I can't really comment too much as I don't know the details of your transaction.
All I can say is that my one-off colour swap model was quoted as being a 12 week build. Due to Jetpower and the Jet World Masters it ended up being a little over 16 (from memory). If you ordered yours recently and it wasn't in stock then I'm not surprised that he is saying that you won't get it this year. He offered me a different colour that was in stock as well, to save me waiting (and no doubt also to move his stock) and maybe he was trying to help you by offering you the same?
I also had to pay the bank transfer fees but that was something that I just accepted as an understandable consequence of paying for something in another currency. It was much cheaper than if I'd been charged a credit card fee.
The fact that I have exactly what I ordered sitting here is proof that he does deliver what he says (to me at least) and I don't see why you have any reason to think that you won't get yours.
