Horrible service

Was booked for service today at 7:00am. I arrived at 7:05 and they said they open 7:15. They processed our information n took our cars into the service area. We waited in the waiting area for 6 hours while staff was doing ups and downs and not communicating anything with us. Around 13:06 we asked how far are they with the cars only to find that they had not even started. 6 hours later they wanted to start with my car n I was thee second person to arrive. No information, no explanation and nothing. I ended up leaving.
