Sandton branch employs *******

I sent my car in for a major service. They use my car to drop and pick me up from the office as well as to run around with. When I left the car with them there was a little over half tank fuel & when I fetch there is almost nothing. They broke my radio face which was locked in my cubbie as they used the radio while servicing. I took this up with the manager who blatantly denied this. They broke 1 of the 4 nuts on 1 of the wheels and said it was like that. 8Mnths later my car is due for next service. I use a different mechanic who claims that USED spark plugs were fitted into my car. The air filter which can only be used once, was forced in the wrong way &
