they refused to work on your car?? that's a bunch of BS....it shouldn't matter WHO you bought the car from. I got stuck on a car like this once and it was a BORN problem car, the dealer sold it and told him to just take it to the dealer closest to where he lives(mine) and i got screwed into working on it. But still refusing to work on your car cause you bought it somewhere else?? What is that all about?? And they said you have to Pay for the regulator?? That's a load of BS if i ever heard it, sorry that's what the 3yr/36K warranty covers.
