Turnpike Chevrolet

I bought a 2016 cruze shortly before the holidays. The next morning I noticed the tire pressure was low, so I put air in. The next morning the same thing. I called the dealership to tell them about it, and that I wouldn't be able to bring it in until the new year. They assured me it would be no cost, and they would take care of me. I get the car there, and apparently there is a nail in the tire. They charged me full price of tire and installation. I believe the nail was in there all along. Not only this, but my credit cars was also charged for warranty they cancelled on my old car. This is the second, and last vehicle I will purchase from this dealership.
