William Simpson Worst Service in the Motor Vehicle Industry

This is the worst and most humiliating service I have ever experienced in my entire life. At William Simpson Nissan in Tokai the white clients receive better quality of service than black/coloured clients do, I say this because, I have seen it myself,I have first hand experience of the worst customer service ever rendered. I had a major service done and upon collecting my vehicle I was informed not everything was done due to time, but my vehicle was booked in at 07:30am. I was not informed that they're shuttle service could take me home and collect me. I returned the vehicle shortly after the service was done because I noticed my coolant, brake fluid levels were at minimum, the timing was out and they DID NOT even notice my front shocks had to be replaced until I informed them of a new weird sound I heard. The worst thing they did was leaving me stranded far from home for a full weekend with a promise I would be collected to receive my vehicle but not one of the service consultants, supervisors or managers made contact with me to inform me otherwise. I was three days without a vehicle, but I know of white clients that have received a courtesy car for use over the weekend. The Service Consultants that assisted me, Service Supervisor and Manager are all equally *********** and are not worthy to work in a Customer/Client Service environment because up until now, even after sending Emails to Nissan South Africa I have received no proper apology or any sign of sympathy or empathy from the dealership.
