How to fix my rf64 hotpoint fridge freezer?

Was given the unit a few years ago, I have only just discovered the door is sloping. The door of fridge and freezer are at the correct height on side of hinge, but slopes downwards towords other side. The seal is only just covering the freezer bit, but it does not cover fridge bit totally, when I put a torch in there I can just about see a bit of light.

I have attempted to play with the hindge but nothing seems to make it better.

Any suggestions?
