Horrible service

I bought a car on the 5th of December 2024 cash the Sales person is James Newman. He was in such a hurry to assist me I had to ask him everything, the disc on the car had expired in June 2024,he told me it is my responsibility to make sure that is updated with my own money, We buy cars will only be responsible for the penalties,he gave me a permit from the 5th to the 24th. On the third day the car started to show engine light pop up, spoke to him,that's when I realized that I was never informed about warranty and guarante. The car is less than 100000km and less than five years however it does warranty, and We buy cars does give any guarantee of some sort. I needed to use that car for business,I paid We buy cars R2250 for service ,they were responsible for changing of ownership which James Newman said it will take within 21 days to complete.I was the one always initiating conversations ,what makes me angry to the core is the level of unprofessional and incompetence, I had asked David to call James on the 11th of December because I felt that he was not taking me serious as a female to enquire about the changing of ownership, he said he will give me feedback on the 14th December. He didn't bother checking nor update me because the issue date on the document states that it was issued on the 11th December. I couldn't use that car and unable to pay my debts because he failed to do him job. I spoke with him complaining about his bad service he just ignored me because he just blue tick me on whatsapp without any response. I wrote a complaint to We buy cars they never responded I guess that's what they do there. Now I have defaulted on my debts because James Newman decided he is not going to do what he was supposed to do
