Poor service

I bought a vehicle in early December 2024 from Weelee Centurion. Initially the sales lady (K) was very helpful and eager to assist with the sales process. While the financing and contract stage were in process I noticed on the invoice that I was invoiced for smash and grab which was fitted,however it was already pre-fitted to the vehicle and when I started to inquire this and some other issues the communication stopped and calls and messages were not answered. I then early in January decided to go to the Centurion branch where I spoke to a floor manager (J) which asked me to send him all the e-mail and whats-app correspondence I had with (K) and that he will look into it and also assist with the refund of the smash and grab that was invoiced incorrectly. I eventually in early February received the Weelee claim form from (J) which I completed and e-mailed back to the floor manager (J). After a week passed I messaged and called him but again without any response. The same trend of failure to communicate is repeating itself. Apart from the invoicing problem the vehicle was licensed in Gauteng but I reside in a other Province and had to re license and do roadworthy check (extra cost) again because of the error that was made by Weelee. The vehicle was also sold without a spare key which I had to sort out and the vehicle had an oil leak which was not picked up by Weelee or the initial roadworthy test that Weelee did. Very unhappy with the lack of service,errors,poor comunication and agreements that were made but not honored by Weelee Centurion.
