I set up an appointment for my car for 2pm for an oil change and asked if it will take any longer to do an engine diagnostics, I was told it will take about 2 hours. I got no call after 3 hours, so I called them and was told pretty much nothing about my car. I walked into the store about 45 minutes later and saw my car was never looked at and it was going to take until tomorrow to get it in.
