Shocking service - defective brakes

A year ago I purchased a high performance car from then Viglietti Motors in Cape Town (now rebranded as Scuderia South Africa). I paid full price for a used sports car and was assured it was in \pristine condition". I was told a comprehensive 190 point service check had been conducted on the vehicle and everything was in order. The car was garaged and covered after I purchased it and I have driven less than 1000 KMs. I took the vehicle in for an annual service and Scuderia charged me over R20 000 to replace brake parts which they claim are worn/defective! I hardly used the car and clearly they either knew of the issue and decided to deliver the car to me with dangerous and defective brakes or they failed to deliver a car that was indeed \""pristine\"". <br> Upon questioning this they offered a 10% discount and refuse to take accountability for there blunder and have no regard for my position.
