My agent was very friendly and professional.
My agent was very friendly and professional. This survey is not in regards to the person that assisted me. I dropped off my vehicle for b service repairs almost $800 and I brought up the fact that my vehicle has been making when I reverse after it being parked for a couple hours. I left my car for about 6 hours and during that time it seems like nobody inspected the issue. I was told I had to bring the vehicle back in on a different day which is an inconvenience. The vehicle was already there.. I left a video with audio of the issue. There?s definitely something faulty or not working properly because the noise the car is making does not sound normal. Again my agent Jamie was great but I was hoping whoever serviced my vehicle could have done a better inspection to identify what?s going on instead of having me bring the vehicle back into the shop.
