AutoNation Chevrolet Laurel

I have bought 4 cars from this dealer and had multiple Chevy's serviced there and I am done with AutoNation Laurel. This was the worst service I have ever gotten anywhere. The service Rep, Jim, didn't return calls, I didn't know what was going on with the repairs and had to eventually just keep hitting 0 to get to someone. Now to the service. One of the issues I had was that one of the tire air pressure sensors needed to be repaired. Not only was it not repaired, now none of the tire sensors work. Additionally, i brought up a transmission issue and Jim's solution to that was to replace the transmission for $10,000. I have subsequently had real automotive professionals look at the issue and it is a repair that can be done for less than half of Jim's quote. So I would like money refunded for the $600 I spent to actually make some of the repair issues worse, I won't be bringing back my car to be held hostage, have a non-responsive service coordinator, and be given price gouging quotes for repairs. I'd never recommend this place to even enemies.
