Checkers not a computicket outlet??

I made a corporate booking through Computicket, received a letter stating that it is a corporate booking with a b-reference number and that no ID or credit card needs to be presented. (Especially since payment was made via eft) I then went to the Checkers in Fourways mall to collect my tickets. First the lady didn't know what a b-reference number was. I had four ladies standing there telling me it doesn't exist, then they tried it on the system and it worked. Then I was told that it is impossible to book tickets without a credit card, even though I had the letter from computicket stating that no ID or credit card is required. Then I was told that the amount is too big they need to call computicket. I had to wait another 15minutes. When the lady came back I was told that Checkers isn't really a Computicket outlet and I need to go to Monte Casino to collect my tickets. Absolutely *********** ladies behind the counter with horrible attitudes!
