Horrible service at VW white river Mpumalanga

I went to service my car at Volkswagen white river and the service I received there was beyond horrible. I booked my car in for a service for Friday and i asked the lady I spoke to, to give me a quote for a major service and she said she was going to phone me back and she never did. Anyway, I took my car that Friday and I was assisted by a lady named Madiro to check in the car. I asked for the quote and she said she would phone me back and after 11:00 I decided to phone them because I was still not phoned. I spoke to a lady named Nonhle and she said she was going to phone back and I had a heated exchange with her because she also said she was going to phone me back band I explained that it was the 3rd time asking for the same thing and that I was going to hold but she assured me and said she was going to phone me back and she did. She came back and said the quote was R26000 and I couldn’t understand what the 26000 was for as I had only asked to be quoted on the major service and she said she’d speak to vw for a service plan to ask if they can extend my service plan. She came back and said that she spoke to VW and they advised that for the service I’d pay 8900 and I said it’s fine, they may proceed with the service. After some few minutes, she phoned back to say the technician is asking if I didn’t mind waiting until after 18:30 because changing the cam belt would take time and I said that wasn’t going to be a problem as long as the car would be serviced. After some few minutes then she came back and said the technician is advising that he would finish with the car the next day and I told her that I needed the car to drive back home and that I’d be ok if VW would give me a car to use to drive back home as I stay in Badplaas which is 120kms away from white river and then she said she’d phone me back. She phoned me back to say I needed to bring the car the next day as the service plan would start working the next day. I agreed to that, I went to fetch the car and when I got there, I asked her for the quote and she advised that she needed to scan it or something and that she couldn’t give it to me. Then i left, minutes later she phoned to say that the technician has advised that he had other cars and that I needed to book the service for Monday. As annoyed as I was, we booked the date for Monday and I took the car there. When I went to collect it, I asked for the invoice and she said she didn’t have it and that I’d get it the next day which would’ve been on Tuesday. Wednesday I phoned her and I spoke to a gentleman named Tebogo I think who asked me about the service and I told him that I was still waiting for my invoice from Nonhle and he said he’d speak to Nonhle about it and that she’d send it. Needless to say, to this very minute, I haven’t received the invoice, I don’t know what service was done to this car. I sent a direct email to Nonhle not so long ago and somebody responded to say Nonhle was out of office and they asked for the registration number of the car which was on the email and I’m still waiting. I’ve never seen such level of incompetence and to think that I was in talks with Clement because I wanted to buy the Tiguan and now I’ll have to go to another dealership because to say the people I dealt with were *********** would be an understatement and I’d never set my feet in your premises again
