U Count payment embarrassment

I am extremely unhappy with Ucount rewards. I made quite a big purchase (R5075.60) at Makro Centurion on 11 April 2015. When the cashier at first swiped my card, it gave a message that there was insufficient funds in the account at which i was terribly embarrassed as i knew there was sufficient funds. I asked the cashier to swipe again. This time i received a SMS confirming the payment was processed, however the system showed that the payment was declined. Although i showed the manager and cashier the SMS they refused to release the goods. I spent two hours in the store shopping and had to leave without the goods. I was very embarrassed by this. Even more frustrating is the fact that the Ucount call centre was closed and there was absolutely no one we could speak to on the phone. The number in the SMS for queries is of no use as there is no one to answer questions or for support. The retailer offered to deliver the goods to my home on monday after the issue was resolved, but this is not a help to me at all as I shall have to fly from Cape Town to Johannesburg to receive the goods as i live in Cape Town and all the goods are for my apartment in Pretoria.
