Pathetic service

I bought a car at we buy cars Dome last year October, when I got home the car showed n engine light I notified them immediately, they refer me to 1 service centre which did not repair the car then they referred me to Bosch service centre where I sat for almost 2 months without a car only for my car to come back with more problems, then I told them to take their car back they refused we buy cars is a ****.
