Special offers..... Not a chance!!!

My husband and I went to Ster kinekor Matlosana Klerksdorp tonight. We are from JHB south and just in town for work. We used our smart shopper points earlier today to buy 2 tickets as I read online that this was an offer. But when we wanted to redeem them for the 17:15 IT movie the vouchers could not be used as their systems were not working right. I asked a worker to help, this was at 17:00, and after a few tries she gave up. I called another worker, Gift Lebeko to help. He entered it over and over, and said its not working due to their system. I then asked to speak to a manager. Which he refused. I asked numerous times, eventually I asked must I put up a scene to demand seeing a manager? He dissapeared, for at least 10 min. Came back without the manager. I asked again. He then just walked away from me. I asked for his name, then he took his name badge off. He then "went" to call the manager again. This was already 17:30. The movie were set to start at 17:15. He then again came out and said the manager is busy. But the place was very quiet. I then asked other staff for the manager's name and Gifts name as he did not want to. We ended up paying full price for the tickets as we did not want to go back to the guest house without enjoying our last night. Needless to say, we missed the beginning of the movie and all the previews which is what builds the excitement, and ended up not having a good experience. There was another couple who also wanted to redeem vouchers on their Sterkinekor cards. They were given free entry. Only left their cards. Why couldn't they take the printed vouchers and do the same??? Are we treated different??? Really upsetting as I wasted my petrol driving to the Pick n Pay to switch the points and then ended up paying full price for something that were already paid for with my points. This is the worst experience ever. Khotso Moeng was the manager. He did not even bother and when I said I am complaining to head office the staff shrugged it off as nothing. I guess complaints don't have value anymore. In the past it would help better service. Now??? Who knows!
