Poor After Sales and Bad Attitude

I bought a 2005 Ford Fiesta ST from Motorworld on the 25th of June. George assured me that the vehicle was not involved in an accident as they are not allowed to sell vehicles that was involved in accidents because they belong to the Blue Chip Dealerships. The vehicle had a few faults on which I told them about and they were suppose to fix it before I collect the vehicle. The vehicle had no oil in and the brake light didn't work when I collected the vehicle. Motorworld had the vehicle for 18 days to repair the gearbox, seat and a few other faults. I got the vehicle back. 2 Weeks after I collected the vehicle, the enjin light came on. Motorworld didn't want to take any responsibility for it. The vehicle couldn't drive. I towed the vehicle to Dekra for a full technical test. They advised me that the gearbox is leaking and that the vehicle was involved in an accident. Motorworld eventually repaired the burnt valve. I was without the vehicle for 30 days. 3 Weeks after collecting the vehicle, the vehicle broke down along the road with no gears. Motorworld is not coming to the party. I am once again without transport and the vehicle is standing in my yard broken. UNACCEPTABLE!!!!!
