Abysmal Customer Service

Glasfit Bryanston I booked an appointment with Discovery to have a DQ Track device removed. The booking said come 8h00 to 9h30. Normally when you book a car in for a service this means come sometime between 8h00 and 9h30. Nowehere did they inform me that the process takes 1h30 to complete and you need to be there at 8h00. I arrive at Glasfit Bryanston at 8h30. I drive into their fitment centre. As I drive in everyone walks off. I choose a bayh and park seeing as the unfriendly staff aren't in the least interested in helping. I then proceed to reception and after waiting a while someone turns up and tells me I was supposed to be there at 8h00 and as a result the booking is cancelled. There is not one car in the place and no work going on whatsoever, but I am told they will not work on the vehicle. I ask to speak to the manager and am informed the manager is not in today. This about sums up the service in this place, i.e. non-existent! I will not be returning to a Glasfit centre anytime soon as a result.
