So man , you got it sorted out ? or It's still not confirmed yet ?
Let me know
Then just wait as Simon8x said , they should go back to you even if I'am not sure if this could happen but he looks like he have more experience. if nothing happens at all ...
From my personal experience, the unconfirmed transaction will be gone completely (you can't see the transaction in the block explorer or your wallet page) in a few days, and everything will just go back to the exact situation before the transaction happens. You don't need to contact the support, but it will be done automatically.
thanks
