Car Repairs

I took my car in January as i had an accident and the driver side door was damange, the owner Dean charged me R25000 to replace my door and give me a fresh paint for the whole car. I thought that was a bargain, only to find that they just fixed the door that was damaged. Now i cant even open my window, the door doesn't even close properly. In winter you can literally feel the breeze coming in. The paint job was amazing but the repairing of the actual damage was not done. When I told him about these errors he only cared about his money.
