Beware Fury Hyde Park

I took my vehicle in for service and replacement of brake pads and discs at Fury Hyde Park and after it had taken them 2 days to get the car fixed when i got to the highway at speeds above 100km/h the vehicle started rattling and when i returned the vehicle to the dealership they said it couldn't be their fault,i then took a drive with the foreman who explained such a mistake/problem can happen when such work is done on the car but the service advisor Shymaal Anandlal was still adamant the problem didn't happen while the vehicle was there for 2 days. I explained to him that i had driven the car 2/3 days prior to bringing it in at speeds above 100km/h and had no issues with the vehicle. The stupidity of the service advisor started insinuating that i was trying to get a free wheel balancing from the dealership which i obviously laughed off because he had forgotten that i paid over R5500 for the work done on the vehicle. This is not the first time i have a problem with this dealership but it most certainly will be the last and im sending out a warning to fellow GM car owners to be very aware of this dealership and their ways.
