Toyota of Richardson

I drove to this dealer after they advertised a vehicle for one price on Autotrader and then found out at the dealership they wanted to add on several thousand dollars for a "loyalty" package that is mandatory. They said it was to reimburse them for work they put into the vehicle. I heard several other potential buyers at the dealership say the same thing regarding their advertised price versus the price in the actual dealership, a classic bait-and-switch tactic of sleazy dealerships. The vehicle also had a warranty sticker on the window but when I mentioned that they said that it wasn't correct (I have a photo of it). Once I negotiated my vehicle and got it home (via trailer) the second time I drove it the transmission went out. I called the dealership immediately and no one returned my call until the following Monday. I asked to return the car due to bad faith since their website says "All used cars on our lot have been inspected to ensure that you are getting the best car for your investment." They would not allow me to return it and have offered no other remedy other than I could trade it back in to them (at a loss) for another vehicle. I've emailed and called multiple people (including the general manger) over twenty times with no solution.
