Poor service Westvaal Nelspruit

I am the owner of a Isuzu D-Max 3.0. I currently reside in Maputo and booked my vehicle for a service at Westvaal Nelspruit. The advisor that handled the booking, was Caroline Rabothata. The booking already was a nightmare as she couldn't spell my email address. She was going to email confirmation of booking which wasn't done as she STILL got the address wrong. I found their email online and started the booking from scratch. The vehicle was booked for 8 November 2022. The dealership was informed that the vehicle is covered by a service plan as well as warranty. I stipulated the issues on the job order. I had the vehicle at the dealership at 06:30 and it was only booked in one hour later. I got several calls during the course of the day. Besides being call SIR all the time, even after I corrected them (I am obviously a woman), they repeatedly gave me prices for parts that needed to be replaced. I confirmed (again) that the vehicle was covered by a motor plan and the parts that was faulty was mentioned by me on the order. Eventually, they called me back, saying they don't have stock and will have to order. The car was returned to me around 16:00 (after they told me the service would take around 2 hours). The vehicle was still dirty qlthough it was evident that they attempted to wash it. I found the invoice in the vehicle. On it, they printed that I declined having the parts replaced. This is a blatant lie. Ater my return to Maputo, i sent them an email enquiring about the above, also about the parts that had to be ordered. My email was sent to Lee von Wiellligh who was going to contact me. This has still not happened after five days.
