Horrible Customer Service at VW Strijdom Park

Pathetic customer service received from VW Strijdom Park from Service Advisor Mr. Shuaym Ali. I booked in my VW Polo for a 120 000km major service on the 8th of July 2022 and my car didn't get serviced because the dealership didn't have the necessary parts to service the car even though the car was allowed to come in for service. The service advisor claimed that there was price changes between VW and my service plan provider, which resulted in the delay for approval process to service the car. I had to fetch my car and re-book it for another day, which was the 15th of July 2022. I took my car in at 07:00am and left it to be serviced. I didn't receive any progress update on the servicing of the car during the course of the day. Only at 16:25, I received a call from Shuaym, which I missed. I whatsapp'ed Shuaym to find out if he was letting me know if the car is ready. I then confirmed that my wife is on her way to pick up the car, since I was at work then. Shuaym confirmed by a thumbs up when I informed him that my wife is on her away to pick up the car. At that time is was 16:48 when my wife arrived to pick up the car and Shuaym said to my wife the car will be ready in a few minutes. My wife waited for almost an hour and I called Shuaym to find out why my wife had not received the car after such a long wait. Shuaym then confessed that the car was not ready after my wife waiting for almost an hour. I then asked Shuaym to arrange transport to take my wife home, so he arranged a courtesy car for my wife which was on reserve tank. My wife alerted Shuaym that the car was on reserve tank, so he drove behind my wife to the nearest petrol station to pour petrol. He poured petrol, however the car was still on reserve tank but he claimed he poured enough. My wife barely made it home with the amount of petrol in the car. Shuaym said the car will be ready the next morning, however the car was not ready has Shuaym informed me that there was a bolt worn out and that was at 18:43 the same day I took in the car for service. The next day at 10:45 after I asked Shuaym when am I receiving my car back he replies saying the bolt will only be available Monday morning and I will get the car after replacement of the bolt on Monday. All in all the service was extremely poor and with no remorse from Shuaym for inconveniencing myself and my wife.
