Bad Service

Took my vehicle for fixing at the branch.It was there for 2 days and I was quoted over R11 000 for everything to be fixed.I paid the amount then fetched it.After 3 days the car still gave me the same problem and it had become even worse than when I initially took it in.I then went back to the store with my husband and we were told that because the mileage is very high on the vehicle we will experience such issues.My gripe was that we paid so much money and we received such **** service.The manager also gave us such attitude by saying that these things happen and there is not much he can do about it.He further went to say that he would need a further R8000 in order to fix the issue.Today as we drive back from home...the engine fault light went on.Now we don't know what this means.We can only assume that the incorrect parts were used and I am not happy at all.I WILL never recommend this car service city because I feel we were **********!!!I am ****ed as hell and I will not take this lying down until I get some kind of justice done for all the money we paid
