Reorder - no reply

On monday I tried to order clothing but due to online purchase limit on my bank card the transaction was declined. After adjusting the limit i tried to redo the order but this time the R450 credit i was receiving on the original order was now invalid as if it was used. I have send 5 mails (Ticket number 347882) and have spoken to an customer care agent on the phone trying to rectify the discounts on the order to get my order placed and as of yet has not received any feedback. One of the items has also now been sold out in the time it took me to get no reply. Can someone please help, cant believe how difficult sportsmans is making it to place an order.
