Pathetic and Dishonest Customer Service

I would rate them a 0 if that was possible. Purchased a vehicle last year November. Highlighted faults to them in the first week of taking delivery , they took it back to address the issues supposedly. As problems become more evident I request the last service on the vehicle only to find that they omitted to tell me about a a possible engine failure and never addressed any of the problems they identified. I am now fighting the fact that my money should be returned and they take back the junk they sold me
