Bad service or is it no service?

On 24 January 2022 I contacted Webuycars to get an offer on my car. A lady called and spoke to me and said they will send an offer through and if I accept it, I can take the car to any branch for payment. After a few hours I received a message that Webuycars are not able to assist with this vehicle. I called them and asked for a reason, was promised that somebody will call back and explain. 25 January still no response so I called again, was told again that somebody will call me back with a response. On 26 January still no response from Webuycars, when I called the lady told me that they do not buy any cars that have any issues or error codes, damages or any problems, because they do not fix the cars. When I asked why 80% of their cars on the floor have issues or problems and they bought it, she said they will call me back to explain. Well, I am still waiting. My car is in perfect condition compared to the cars under R100k on their floor. This is the 3rd time I have struck out with webuycars, previously I wanted to buy a car and experienced no or bad service from the sales person. I am just wondering why they advertise that they will buy any car, there and then? In the media you hear how they built this company on sound professional and good practices, but with all the lying and no service, I really wonder if this company is only interested in the money now. What a bad experience, hearing their adverts on the radio with the lies make me nauseous.
