Toyota of Richardson

Toyota said I must continue to work with this dealer because I brought my vehicle in to them for diagnosis, but this dealer constantly wouldn't do their part, finally refused to contact me, and refused to work with Toyota about the issue and inform me about it. Caused me problems with warranty/buyback, because Toyota is saying they haven't heard updates from the dealer, so their last info is that nothing is wrong with my vehicle. The dealer's reason for this was that you bought the vehicle from another dealership so you shouldn't have brought it to us in the first place. But I brought it to them for a second diagnosis per Toyota's instructions. You're supposed to be able to take your vehicle to any Toyota dealership.
