Horrible after-sales service and no response from We Buy Cars directly after selling me a faulty vehicle

On Saturday, 17 January, we bought a car at We Buy Cars. Unbelievably, on our home (directly from We Buy Cars), we immediately experienced a lot of trouble with the vehicle. We immediately conversed with them when we had to stop next to the road on our way home. Up to now, 22 January 2026, there had been absolutely NO resolution from We Buy Cars. Unfortunately, their after-sales service is not us upfront as all their sales techniques and adverti*****ts.

I attach my correspondence to them below, as nobody at We Buy Cars feels it worthwhile to respond at all.

I am writing to formally request the immediate cancellation of the purchase agreement for the vehicle acquired on Saturday, 17 January 2026, and a full refund of the purchase price. As documented in my initial report submitted via your website shortly after 19:00 on the day of purchase, and in subsequent discussions with Mpho, the vehicle experienced a significant mechanical failure within 60 km of leaving your dealership. Timeline of Events: 17:05 (approx. 60 km from dealership): A warning light appeared, and the engine began idling erratically (misfiring). I immediately notified the salesperson via photo and video. 18:26 (Alexandra area): The engine light flashed on and off, and the vehicle suffered a severe loss of power, struggling to reach 70 km/h. I pulled over and provided a further video, photo, and voice note evidence to the salesperson at this time. Arrival (Meyersdal): Near the Michelle Avenue offramp, the engine warning light became a permanent fixture. I drove ±2km further to my partner’s house, where the vehicle has remained stationary since, as driving it further risks catastrophic engine damage. This vehicle was sold with a "Gold/Certified" sticker, supported by clear mechanical, electronic, and Dekra reports. The fact that it failed within four hours of purchase is a breach of the quality and reliability standards promised. Given the severity of these faults and my requirement for a dependable vehicle, I have lost all confidence in this car. I request that you arrange an on-site assessment immediately, as the vehicle is not roadworthy. I look forward to your urgent confirmation regarding the cancellation of this deal and the refund process. I am currently without transport and require a resolution as a matter of priority.
