My worst service experience in 10 years

I had the worst service experience in my 10 years of servicing my vehicle! Firstly, when I called in to book the service, my call was passed from one person to the next until I complained. Secondly, I had called the Randburg number on the website, and was not notified on the phone that they had closed that one down and that I was talking to the Fourways service centre. I was told to drop the car off anytime between 7h30am and 9am. Thirdly, when I got to Fourways (just after 8am) I was then told by my servicing consultant that they do not do shuttle services or wash the cars when they are done (all to save costs). But then when I was sitting trying to get an Uber, one of their drivers came around asking where I was going and if I needed a ride (which meant that they do do shuttle services). Fourthly, and the most shocking, I was called after 4pm to be told that there is more work that is required (worth R20k) and that they need authorisation. When I asked them to provide a quote and I will get alternative quotes, I was then told that they did not service the car at all and that it would only be done the next day. The service consultant even tried to make it seem like I arrived late that morning and they already had a long queue. I left my car with them so that they do just the service, and I was told that they would be done by 1pm and the consultant would call me. The following day, I called them after 3pm asking when if they were done, but the consultant said they were waiting for the person (who had gone out) to test-drive the car. I took an Uber to the place to collect my car, and was there at 5pm. But I was then made to wait again because the servicing consultant had to do my invoice. I only left there around 5h30pm. If you need to service your car, I would recommend that you stay far far away from the Williams Hunt Fourways service centre.
