Bum car

I bought a car from Weelee under six months ago. The car was financed through MFC. Weelee provided a clean bill of health through a Dekra certificate. The car is now useless to me as it's in the workshop with bent valves. It appears the engine was shoddily repaired prior to the sale to me. Whatever was repaired, the engine was not put together properly again, and a part broke off and destroyed the timing belt. I have written to Weelee about the matter twice now and there has been no response.
