I made an appointment to have my vehicle worked on...

I made an appointment to have my vehicle worked on at 8:00am. The job was booked for 2-2.5 hrs. I had made arrangements for my coworker to pick me up before work and drop me off after work at the dealer. I came back at 4:00pm and the car was still not finished. Of course they had an excuse which is neither here nor there. The important part is that I never received a phone call on an update. I was forced to sit at that dealership until 5:45pm which is when I actually got into the car and drove home. This is completely unacceptable. All I needed was a call saying my vehicle wouldn't be finished on the time frame it was supposed to be. A simple 2 minute phone call could have saved me 3 hrs of waiting around. Piss poor customer service for the most simple tasks.
