AutoNation Subaru Arapahoe

I have been going to Autonation East on Araphoe since 2003 when I bought my first Subaru. However, after yesterday, I will be having my maintenance done elsewhere. Granted I now live in the mountains and getting to Autonation East is harder to get to because of all the traffic we have now, but that is not the real reason. After I left my car, I was called and said that I needed new brakes on the front tires plus a few more repairs that were not covered by the . I gave the "go-ahead". Then I received another call later saying the mechanic had taken off the wrong brake pads (the ones on the rear) by mistake and thrown them away. They said they would replace the rear brake pads for free since it was their mistake but I would have to pay for the resurfacing of the rotors which was another $150.00. I feel this was unfair...I did not need to have my rear brakes replaced...it was a mistake made by the mechanic. While Autonation paid for the new brakes, I shouldn't have had to pay for the resurfacing rotors. My bill that started being approximately $850 ended up being $1318.88. While the staff at Autonation was very friendly, I feel I can do just as well at a place on the west side of town. The other things I really did not like was that they disconnected my battery during servicing. I understand that but now all my settings are off...date, time, etc plus my Sirius radio settings. While that might not be such a big deal for young folks to reset all this, it is for me. I am 75 years old and will probably need to go back to the Car Toys for help in resetting the Sirius. After spending 7 hours with my car, would it be too much to ask that they reset the date and time?
