made to pay for things under warranty

my car broke down on sunday 29 march and was towed by AA which then took in the car on tuesday morning to bramley to replace and engine mount bolt that had fallen off. upon collection was told to pay in R318 for labour yet the car is still on warranty. please note the gearbox was fixed by suzuki bramley again so if anyone did not tighten that bolt it is their workshop and yet i had to pay in for that. i spoke to deon and he said he would get back to me. called head office and spoke to hamman and he took my details again which he had alredady received from sammantha and never got back to me . the logo for suzuki is the suzuki way of life and all i can say is since i got that car which was supposedly brand new it has been nothing but a streneous way of life that car breaks down at least twice a year and at most 6 times a year and amidst all that i still get tossed between tow trucks and bad customer service
