Car Damaged by Super Tyre Employee

Let me start by saying that our family cars have had their tyres since 2002 fitted at Super Tyres. Yesterday, on Saturday 30th June 2018 was a bad experience with Super Tyres when I took my car to Super Tyres -South Coast Road - Clairwood - Durban, to fit new Michelin tyres and lower arm controllers plus wheel alignment. When I arrived at home around 12H30 I noticed that the drivers side front bumper next to the wheel has been badly scratched which is as a result of a Super Tyre employee driving my car either out of the bay and or into another bay. Worse the employee does not even have the decency to inform me about the accident/incident. This is unacceptable and Super Tyres' employees should stop this practice of driving customers cars since they are not the insured drivers of these cars. I now have to get my car fixed at my personal expense. I doubt Super Tyres would take responsibility of any of its staff members who damaged my car nor any customer car for that matter.
