Horrible service from webuycars joburg south

What a horrible dealership with such horrible customer service! Both customer service and Johannesburg south branch I bought my car (BMW 1 series) in January via Finance with Webuycars , it took over 2 weeks for that car to fetched and i was told that its cause “it needs to be in perfect condition/as new as possible since it is finance”. Nkateko was my salesman. That guy barely ever would communicate throughout the process , i would have to be the one to beg for update. Come the day of collection , i got there at around 12/1 yet i only left at 4pm because Nkateko decided to go to lunch even when i had communicated that im on my way. I waited for hours for him. Fair enough , i get the car. Surely after a month the car starts having water problems (WHICH WAS NOT ON THE DERKA REPORT) , i go to them to report the matter at the brunch , all they did was give me a bucket of water to pour for me to drive back home and he told me he would escalate the matter and i never heard from him again. Then a concern is then logged because ive had to go back again. Even had to go as far as claiming from my warranty (following day after fetching it from Bosch before i even go home , it started signalling again for water) Bosch has tried fixing the car , surely 3/4 times before they finally told me to go back and ask for my refund/cancellation because the car has started building up pressure meaning its clearly not going to make it. I go back to south brunch and again this Nkateko guy is being hidden cause each time ive been there “his apparently off”. Recently on the 23th of August (bare in mind ive been back and forth with this issue since March) my car starts again same issue , following day i go to the dealership to tell them that i do not want this car. Yall have tried to fix this but still no success. I have documents from Bosch saying they cant fix the car meaning i need my refund/cancellation. They log a concern yet again Grace Nywenya is the one currently handling my case and wow horrible , she does not communicate. I have to beg her to inform me whats happening so far. The manager who helped that day to log the concern has never communicated with me since that day 23rd. Its been over 3 weeks now without any progress with this refund , hardly communication nor update yet im going to help another date where ill be paying for a car i dont even have in my possession. Horrible horrible service!! Ive got pictures , emails , documents showing how far off ive been having issues with this car and no one is attending to the matter with urgency
