Dude! This is going to be a hard lesson for you
You made so many mistakes here I don't know where to start
1. Any time you are asked to wire money by someone who is supposed to be paying you, it's a scam ALWAYS
2. You apparently felt early on that you were being scammed, but you continued to play right along. And you wait until it's painfully clear you have been scammed (check bounces) before taking any real action.
3. You turn to a internet message board for guidance, when you should have been communicating with the police, the bank, etc....
And as others said the "contiuing calls" reeks of shens, they have your money and I see no reason they would call you again, unless they think your stupid enough to wire more money.
If this is real I feel very sorry for you, but there is not much anyone including the police can do at this point, unless you get real lucky and the theives were stupid and left a trail (not likely). YOUR MONEY IS GONE, and it ain't coming back. Try and get over it the best you can and be smarter in the future.
