RIM NOT FIXED PROPERLY! CAR IS RATTLING!

I hit a pot hole on Friday. This caused a dent on my rim and my tyre was torn on the side and so I sent my wheel to TWT Meadowdale on Thursday morning 24 March 2016 to get the tyre replaced and rim repaired in time for me to drive to Durban that afternoon. When I came to collect and pay the rim and tyre seemed fine. On the drive to Durban I noticed that the car had been rattling and pulling towards the newly replaced tyre, so I went back to TWT to find out what was the issue as this wasn't happening before. <br> They checked the car and found that the rim was still a bit skew which is what was causing the rattling and pulling to the side. They asked ME to liaise with their subcontractor(Wheel Collision) to correct their error. Who are now claiming that I hit a pot hole again which is not true as I didn't hit a pot hole otherwise the tyre would have burst again. It is not my responsibility to do this back and forth with TWT's subcontractor! If the rim was beyond repairs they should have not taken it for repairs in the first place and charged me for the repair. I want my money back or this Rim repaired because I'm not driving around with a skew rim after I have paid for it to be fixed!
