Please help! Can't take pole down, stuck 3 locking screws

I'm moving out shortly here and my pole is stuck!! :[ Landlord needs to show place tomorrow! When I put the allenkey in any of the 3 hex locking screws and turn counter clockwise, they will not budge a smidge. Even tried using a wrench. Alternative methods?? Suggestions? A spray, put something frozen on it?? Help!
