scamming people with faulty vehicles and extremely poor service

I bought a mazda 3 from them last month, the following day the window silver lining was falling off and i soon discovered that it was replaced using glue and it had dried up. the key had low battery that it didnt work the following day. they are still failing to pay my registration after telling me they are in the process of registering the vehicle. they said i must register they will reimburse , it is still not happening. poor cars and customer service.
