BAD BAD SERVICE

My insurance appointed auto magic to fix my car because I had accident during the festive, they estimated that by 09/02/2018 my car will be fixed then I took my car to them on the 25th of Jan 2018. Then on the 09/02/2018 they said my car is ready for collection, I went there to took my car and went home, when I’m at home I see that many things went wrong the bumper wasn’t straight, the inside motor covers were lying in side my car, I had to go back to them on Monday 12/02/2018 to complete my car but still the wipers and cruise control of my car wasn’t working but they fixed the bumper and inside covers and they said they will take my car to Renault for report that will determine whether the wipers and cruise control is not working cause of the accident or not, so yesterday 15/02/2018 I went to them again so they can take my car to Renault , they said I have to agree and sign that if the report come up saying the wipers and cruise control is not working cause of other reasons not the accident I will pay R980 but if it saying it because of the accident they will be liable for that R980 than I agreed and signed. Late yesterday the report comes up saying it not clear what cause the wipers and cruise control to not work but I was forced by auto magic to pay R980 for nothing cause the report didn’t say wasn’t the accident that cause the wipers and cruise control to not work I paid for what I didn’t signed for, I’m extremely hurt.
