Worst Business ever

How I wish I had listened to people who told me that these people are a bunch of ******. I took my car in on the 04/06 and up to date its still been there because they could not figure out what the issue was. When they finally think they have figured out what the issue was they made me buy a part which I did but now they are saying the issue is with management and they cant fix it but I have to pay R8000 because they replaced that part which was not the issue and before they can release the vehicle that is still not fixed. I mean what sick business is this? No matter how stranded you are do not take your car there
