Car Repair

My vehicle was fixed by this service provider and the vehicle was fetched by myself last week Wednesday and had to be returned the following morning in Polokwane. I only drove the vehicle for 10 kilometres and it overheated on last week Wednesday and gave the same problem yesterday in Nelspruit after having it only for 6 days since collected last week Friday by my husband which it did not present with before the vehicle was fixed by BMW. Car overheating and mixed oil and water after one of the guys in Polokwane forgot to put coolant after the vehicle was fixed for not starting. But I was not given a apology and explanation for inconvenience and the car looses power and also had to pay close to 30 000.I had to arrange towing and I also have no vehicle my car is out of service plan so have been popping cash every time and took my car to the dealer cause I needed it to be fix it was only computer box now I have a overheating problem.
