I have taken a 2x4 block and applied pressure to it with a ratchet strap on the door of the safe. No result. If it helps, the handle won't completely turn shut either.
If the handle is wedged between the open and closed position, there is likely something broken within the boltwork of the safe itself.
If it's under warranty, the manufacturer may replace the safe, or send replacement parts. If it out of warranty, don't hold your breath. They design these safes to be disposable. You use it until it breaks, throw it away, and go buy another.
