Appointments always run late. Technician is very overbooked. I have had 2 incorrect appointments scheduled by online and showed up without tech thereon one trip. Second trip could not get car hooked up after 8 hours I had to leave and try again. Not at all correct with times of appointments. We all have to work also. Wish they could get a earlier opening and another tech to assist the one already there. Seems like they have too many appts and cannot service them well.
