Poor service and awful customer care

I drive a VW Golf Chico 1.4. I took my car to Shelley's VW in Salt River for a service on 28 September 2017. I had been there previously and dealt with a wonderful man by the name of Keenen who unfortunately no longer works there. My vehicle was due for a service and I was charged R1 000.00. As I live close by, in Observatory, it was convenient for me to take my vehicle to Shelleys. I collected my vehicle on 28 September and drove it home, roughly 1 km. I then went away on holiday until 4 October 2017. When I returned and drove my vehicle, I noticed that the battery light came on and the vehicle was overheating. I immediately contacted Shelleys and explained my problem to the mechanic. His immediate response was to tell me that he was unable to assist me until Monday 9 October and that the problem was going to "cost me more money." I told him that I needed my vehicle and that I was not happy with the service that Shelleys had done on the vehicle. His attitude was that it was not his problem and he was singularly unwilling to be of assistance. Upon taking my vehicle to another mechanic, it transpired that the fool had failed to replace the alternator belt which was why the battery light was coming on and the car was overheating. Whilst I recognise that everyone can make a mistake, it was the mechanics awful and unhelpful attitude and his money grubbing response to my telephone call that will move me never to entrust my vehicle to Shelleys in the future, nor do business with them. Be forewarned, vehicle owners!
