What happened computicket

I had booked 5 tickets for the Lipizzaner shows on the 17.05.15 and had received my booking ref number. I had given my booking ref to my closest checkers in order to receive my tickets. I was advised that I had not paid for the tickets and owed R1050.00 I called computicket and was advised that the manager of the checkers needed to call and sort out the booking. After 30min it was established that I had indeed paid for my 5 tickets, and was given the incorrect booking ref. No apology was provided. I had paid for tickets on line and was inconvenienced standing waiting for over 30min for computicket to sort themselves out. If you are going to provide a service, make sure it works
