Gay Buick GMC

I purchased a used 2018 GMC Sierra 1500 truck from Gay Buick GMC on April 1st 2023. The dealership fraudulently overcharged me a total of $498. I only met with and spoke to the sales associate, John Pigott, & the finance person, John Pack. I made it clear to John Pigott that I did not want to pay for any additional services or add-ons. John concurred and responded back repeating what I told him. John then went back to the used car sales manager, Joshua Block, and returned a few minutes later. He had a piece of paper where he had written numbers on it. He showed the final out the door price and once again confirmed that I was not paying for any additional services or add-ons. John stated that I was only paying taxes, title, and administrative fees. I then spoke with the finance manager, John Pack. I signed several documents. I don't remember seeing the line item charges however I was charged $99 over invoice and $399 for a service.
