Car Service City trying to **** us

Took my car in to Car Service City Rivonia for an inspection for a major service. They charged me R680 for the inspection and came back with a R47000 quote. They said the car needed the timing kit changed, water pump, fuel pump, control arm, battery(which is brand new), all 4 brakes and few other odds. I declined the quote after them trying to start the work without my approval!! I then went to another car repair service place in Rivonia, they did all the same tests and turns out all the car need was a full service and some coils changed!! Please people be careful when going to this place as they are clearly trying to **** us!!
