Briggs Kia

I went to Briggs Kia Dealership to have my car serviced for an air bag malfunction only. The courtesy check given for my light repair was false.
When I left the car lot my right light signal was clicking rapidly but I thought it was a new system. Not knowing, a friend of mine said my back tail light and reverse light was out and also the front left headlight. I got this "fixed" Thursday, *** at the dealership and the issue occurred *** but I'm sure it was the same day but I had not noticed it. The next day, ***, I called the dealership and told them the problem. They said I may have an electrical problem. I told them that I cant come to *** because of my schedule but if I do, would I have to pay again. He laughed but I wasn't having it. ***, the service tech I talked to, said he would talk to his boss and call me back. Never did. Later that day I looked and found that my plug to connect the tail light and reverse light was unplugged, and pushed down like it was hidden which I find fault of the mechanic for this. I would like to be reimbursed for this service and no longer will I go to them for any services period. This was my first and last time going through them for anything.
