Master Cams is a big NO NO

My boyfriend and I sent our car to Master Cams on the 03/10/2020 for repairs they charged us for the first quote R10700 and we payed the amount. When we drove the car home the car was leaking water and we returned the car and they replaced the thermostat. then the vehicle only drove a week then the vehicle was making funny sounds and couldn't start after that. we return the vehicle and they mention that the timing chain jumped and bend valves. they then denied that they were told to replace the timing chain which will bend the valves again. The vehicle was standing for months before they worked on it. They kept on postponing to work on my car until I got fed-up and said I'm towing vehicle .They then demand me to pay R10000 to receive my car. I then had to pay the R10000 to tow my car away on the 07/12/21.
