I made an appointment for a standard 5k mile service for 7am. I was told I only needed a tire rotation and oil change. I have been sitting in the customer lounge for over an hour and a half, and when I went to check on the status they said "about 10 more minutes." If I knew this was going to happen, I would have gone to Walmart and had the same service but would have been on my way to work in 20 minutes. The reason for even making an appointment was so I could get it done before work since that is the only time I have to do it. Now I'm late for work and still waiting on my car. Not sure why they even bother asking their customers to make appointments.
