BAD REPAIR TO VECHILE - NO WARRANTY GIVEN- DAMAGE

MY BROKE DOWN. PRO POWER CAME AND TOWED MY CAR.. WAITED MORE THAN A WEEK FOR MY CAR AND WAS TOLD THEN IT WAS A ELECTRICAL PROBLEM. HAD TO WAIT ANOTHER TWO DAYS FOR MY CAR. RECEIVED MY CAR BACK AND THERE WERE BLUE MARKS - DAMAGE - TO MY CAR.. AS IF THEY BUMPED IT WITH A BLUE CAR... MARKS OF THE PAINT VISIBLE ON MY CAR. PAID THE MECHANIC R1900 FOR MY CAR. DROVE FOR NOT EVEN 2 WEEKS AND MY CAR CUT OUT AGAIN..PHONED MECHANIC BACK AND TOLD HIM. HE TOLD ME THAT I HAVE A WARRANTY. THEY FETCHED MY CAR AGAIN.. MY CAR HAS BEEN WITH THEM FOR ANOTHER WEEK. THEY HAVE NOT POLISHED OUT THE BLUE MARKS - DAMAGE TO MY CAR AS PROMISED. THEY STRIPPED MY ENGIN... AND PHONED ME AND TOLD ME THAT I NEED TO PAY NOW R4900 FOR THEM TO REPAIR. I HAD TO PHONE AND PAY ANOTHER PERSON NOW TO TOW MY CAR BACK TO OUR PROPERTY. NOW MY CAR'S TOP OF ENGIN IS IN PIECES. I CAN NOT FORSEE PAYING AGAIN FOR THE CAR.
