Firestone Complete Auto Care review: Unauthorized charges

Unauthorized charges of; state inspection ($20) and parking brake system ($35.40) and TPMS diagnostic ($48.99) and applicable taxes that were added due to the extra charges. Car dropped off for brake pad replacement only. when called by Debbie to explain work needed and authorization for work, she listed tire replacement, tire sensor replacement, and brake pad replacement. My daughter who took the call told her she would call her back with authorization. she called me and I instructed only the brake pads, and we would get tires at another place. Debbie informed her on the call back "that she would fail inspection" this statement to her only meant if she got an inspection she would fail, which is not what we authorized or asked for. By admission Debbie agreed she only authorized brake pads at that time of the call. according to Debbie, when I spoke to her in person, the inspection was already completed when she called, and they could not take it back. Essentially doing work without authorization and charging us for it. The other items were just placed on the ticket without any mention or need. When I asked Debbie why, she said the parking brake is electronic and they have to engage it when changing the pads, I had my other vehicle worked on at the same Firestone a week and a half earlier and I have electric brakes as well and I was not charged this nor told they had to do this. I have no idea what TPMS diagnostic is or why they had to do it, she gave no explanation. I sent my daughter to drop it off because I felt comfortable at the time due to how well my first experience was, however, now I feel they took advantage of a young person and added all this unnecessary work and even after being only authorized for brake pad replacement, continued to add services without our knowledge.
