Sterling Mccall Buick GMC

First oil change in my new truck. Asked them to look at some issues while they were at it. Mainly a noise coming from the left from over bumps. I was told the leveling kit I installed was causing the problem, but they couldn’t tell me how or why. They actually couldn’t tell me anything about it. Because they refused to even look at the problem. I was standing right by the mechanic telling the service advisor that when he took the tire off and saw leveling kit he didn’t going any farther. I never once asked for it to be covered under warranty, never said I wouldn’t pay for the diagnostic. Told them I would pay for the repairs. They still refused to look at my $85k truck that has problems before the first oil change. I might add when I arrived to pick up my truck. There was no one outside, to greet me or inside for that matter. No one at the parts desk. Literally no one asked me if I needed help for a solid 20 mins. Finally I decided to set my alarm off on my truck from my phone. Still no one even seemed concerned. I finally had to walk to the back of the lot and grab an employee. This is hands down the worst service shop I have been too in my entire life. Stay far away from this place.
