“I sent this email to the survey for randy marion dealership on statesville rd here in huntersville nc. Again I do not want the vehicle back as it is too much risk for me, my family and my work. It put me in a dangerous situation from being stuck in the street and dealing with an angry passenger. We must get this resolved immediately. I am losing money. I need a dependable vehicle. The sales part went as expected. A lot of smiles and very engaged in conversation. The sales guy mike was very nice. No pressure. The problem is after the care was signed for. …”
