Lack of quality assurance

My Car was taken for repair at Proline A division of Renew-it. And a Auto n general approved panel Peter. I have recieved a very poor service from the proline team. They failed to replaced the engine mounting, the car is vibrating I am not even convinced that the team know what they are doing, I took the car to Toyota Edenvale and they confirmed that engine mountings were damaged, there is some funny sounds that I hear, I now thinking of taking the matter I think this company should have their Licence revoked. They promised to get the parts by the 3rd, on the 4th j will get a call to bring the car it's the 5th today I have not received any phone call, I called on the 4th spoke to the service urgent who promised to make follow up with the buyer, there after I will get a call, no call came through. I personally think these pple don't know what they are doing or they have no respect for black pple. The cost for repair was 60K. I paid 15k access but what I got was a very bad service no quality assurance checks. As a result a back yard panel beater is better than Proline

Auto and General team were contact they promised to send an assessor which never happened.
