[URL Removed] refuses to deliver order sooner!!!

I purchased a PSN Plus 12 Month Membership Voucher (order #***) through [URL Removed] on 02/04/2015. I payed for item through EFT from my FNB account to their FNB account. Over the Easter weekend I have checked the status of my order and it maintained a 'Awaiting Payment' status which bothered me abit as I payed for the order on a weekday. Contacted their support@kalahari contact centre and was told my query and proof of payment was sent to their accounts department and I will receive a call back once they have escalated it. Call never came. I called for the fourth time now today (08/04/2015) was told that the same problem has happened to a few clients who payed through EFT to their FNB account. They mentioned then I will get reimbursed. This made me furious as now I have to place the order again (item might even be more expensive now) and have to wait the 11 working day delivery time again which is pathetic! They should either make sure my order comes within 5 days or I'm never going to do business with them again. I will make sure friends and family know about this!! I feel this is unfair to the consumer as the problem happened on their side.
