Poor Repairs and Unhelpful

I recently had my car repaired at Sandown Motors Rosebank, paid almost R40K to have the gearbox repaired. Last week Wednesday the car packed up again, I called the dealership and was told to get the driven to them, which I manged with great difficulty. The car kept jumping out on gear every 100 meters. They checked the car and has that the car be booked in. I requested a loan car for the very first time. told that they would arrange, ever since I kept calling them and told that they are delivering a car to a client and will have one ready later, this for three days, unfortunately just lies and deceit. The dealership lost my trust never again will I use this dealership. On Friday I was told a car was arranged and an hour later another excuse that the use car is over 55 days in stock and therefore they cannot loan me the car.
