MARGATE Auto Refinishers, broke my car

I left my car (polo 1,6) for minor paneleating repairs as I'd been involved in a minor accident, and the day that I fetched it in less than an hours in 30 minutes the oil light comes on and the car starts losing power.... Mind you I. Drove the car to the panelbeaters it had no problems was using it daily.... As soon as I called them and mentioned it to them... They only called and asked if I was OK... But I had to take the car to a mechanic, put parts and fix myself....
