Bad service

My car is insured with Discovery Insure. I was referred to Dent Tech in Strijdom Park, Randburg, for a repair. It was a minor repair, yet my car was kept there from the 15th of January 2019 to the 25th of January 2019. In the meanwhile Discovery had to pay out more for the rented car, because the car was kept for so long. I fetched my car on 25 January 2019 and I signed that the repair had been done satisfactory. When I got in to drive my car home, I noticed that my car's remote was broken. It was in a perfect condition when I brought the car in. I also noticed that the cigarette lighter was missing. I reported this to Ricardo, who proceeded to take photographs of the damages. He promised to sort out the problem by Monday, 28 January. I had no response from him. Later I was phoned by Riaana and I said the same to her. She promised to get back to me. She didn't. I reported the damages to Discovery and they said they would investigate the problem. I said I would be reporting this on Hellopeter. Today, I was stranded when the remote stopped working all together. I phoned Dent Tech and said I was coming to sort out the problem with them. The owner was ready for me. He was ready for me, he said, because of the threat that I would put this complaint on Hellopeter. The "after" photographs, that Ricardo took on Friday, when I reported the damages to him, were now presented as the "before " photographs and I was made out to be the ****. They say there was no cigarette lighter and the remote was broken. This is not true. Also my car was on still on 167 thousand kilometers when I took in the car. When I got it back the car was on 168 thousand kilometers and the petrol tank far below empty. The clock of my car was on the appropriate time when I gave it in. When I got it back it was showing 7:00 at 16:00 hours. The repair was to the door and it was minor. I cannot see that here was a need to disconnect the battery. I would never recommend this company to anyone.
