Audi Sandton provides very Bad Service

i urge everyone that reads this post to never go to Audi Sandton for a car Service or even by an Audi for that meter course their Service stinks, i took my car there for break change the first time they told me that they couldn't change my breaks even though I told them that the car is not safe to drive i had to return the car , they kept my car there for two days fixing the breaks course the car became worse , a consultant called Nick had a bad attitude with an arrangement to pick me up after the car was finished the only solution he had was to leave my car with the security gourds at the gate for me to fetch it there i mean how useless can one be
