Poor service and workmanship on my Vehicle

My car was booked in for Gearbox replacement at New Vaal Motors the glen and I was **** to that the car is in the workshop while the car has not even been stripped.Only after four days I was told the truth by the Workshop Foreman that the gear box has only been stripped yet you had the car for more than 3 days. .My husband followed up with you and requested that in the meantime if you can provide me with a courtesy car as I made plans for only the period of 5 days I booked in the car with New Vaal Motors. Your response was that you have a lot of customers and its not possible to cater for invidual needs yet the dealership was in the wrong, Which is a total contradiction of the Consumer Protection Act.I then collected the car on the 3rd March 2016 which apparently quality inspection was performed on the vehicle and it was good to go. The following day on the 4th March 2016 I drove the car about 10km and it brokedown again.Never Again take my car at New Vaal for service or repairs...Unprofessional at its best.
