Before anything, make sure the card was fried and not your PSU or PCIe slots by a test on another board/PSU
It's already in the repair shop. too late for that.
If they refused to return and you bought it less than a year ago don't freak out, just go to Asus and ask them if you can apply for RMA.
Does Asus have a representative in Lebanon? If so, where?
EDIT: maybe this?
