Antelope Valley Chevrolet

I am unsatisfied with the service that I have received from AV Chevy I drop my vehicle off more than 3 days ago I have gotten only one call back I've called multiple times and they keep telling me that they're going to call me back and they don't I drop it off for a simple abs sensor my vehicle was inspected this year for an extended warranty and approved by Chevy but there now telling me that my warranty is void because there is a leveling kit on the truck which was there when I purchase it also my third brake light was leaking which cause damage to my interior headliner Iris the tech lady has been nothing but rude at first talk with Roberto the main guy everything seemed fine I spoke with him this morning he seemed agitated which makes no sense because his vehicle has it been sitting there for 3 days so when asked do I recommend AV Chevy no I do not service is not good truck awesome truck go to a different dealer
