Weelee no aftersales service backup!!

I bought a car in 2023 with them and the engine light was on and I was given the reassurance that it will be solved. After several back and forth whatsapps and emails nothing happened. Car was taken to their mechanic and light was off for few days and returned. Car was taken to mechanic that they specify now and he identified the problem. Now I get nobody at weelee to speak to me and return my calls. This is outrageous as they were quick to sell the car to me but does not back up their after sales promises. My next step is legal action now as the car is giving more and more problems due to this engine light.
