I hate the car AUTOPEDIGREE sold me

I bought a vehicle in April 2015. All looked fine at the dealer until they deliver the vehicle to my house. Few minutes after they left I found the car was not serviced, the disc was expiring, the windows were falling off the rail, dents were not fixed, I was shocked because that was not part of the deal. I called and told them n they didn't sound suprised, they told me they will call me back so I can bring the vehicle in and all that will b sorted. For 4 months I called 3 times a week and they kept hanging up on me with a promise that they will return my call, no call was returned. I went back to the dealer a few times and was told all will be fixed but I need to come back when the manager is there. In August, I went back and finally met with the manager who was very rude and treated me like a crazy person. He told me he can't help me. He even said he did me a favor by selling me the car. Made me feel unworthy of his assistance.I right now m stuck with a car that I hated from the day I bought it because of people who lie about anything just to seal the deal. I have bought 2 cars before elsewhere and haven't seen such bad service.
