We had a good sales experience when we purchased a new Rav4. However, we sold it and I have been trying to get a hold of the finance department to cancel my warranties for the past 3weeks and can't get anyone. The operator took my name on 3 occasions saying someone will call me, still nothing. That tells me that after you buy the vehicle they are done with you. They don't even know why I am calling and I cannot get to talk to anyone.
