Empire Hyundai

I originally went to Empire for a recall that was taken care of. As I was pulling into the dealer, the check engine light came on in the vehicle stalled. I authorized them to do the Diagnostics to find out what was causing the issue. Being that it was not safe to drive home I was given a ride which was wonderful. I did have an issue with the car stalling before that was repaired by the dealer I purchased from. A few hours later I was told it was the oil control valves they tested out of parameter. I was quoted a cost of $705 plus and oil change. I was told my extended warranty would not cover the repairs. I originally agreed to have the vehicle repaired. I was also told one part was in stock the other would be in in the morning and they would repair it then. I also spoke to the dealer where I purchased it in March and let them know what was going on. They asked that I bring the car back to them to make it right. I called back to cancel the repairs since it wouldn't be done until the morning I didn't think it would be a problem. When I called and stopped the repair I was told the car was already taken apart I would have to pay another hour labor to put it back together. I refused, parts were left inside of the vehicle I have no issue with that. They were advised the tow truck was on the way to get it and the car was placed outside. I was informed the vehicle needs to be paid for before it could be released which I understand . I tried to pay it over the phone and was told I could not they couldn't take the credit card over the phone . So I had to drive the 30 minutes to get there to pay it. it was parked where the tow truck could not get to it so the driver asked if someone could help push it he was ignored and I had to do it. So now I will Fast Forward 2 days later the car is at the dealership where I purchased it, the parts that were recommended to be replaced by Empire to fix the problem were replaced by them. That was not the problem. So I paid $270 for Diagnostics problem was not solved. What would have happened had I paid the 750 and the problem still isn't resolved? Also very annoyed that I was told warranty would not cover it yet it was covered where it is now. I will not recommend you to anyone for service.
