Shocking Service!!!

I had placed an order through [URL Removed] but I was unaware that I could only use 5000 eBucks at a time. My order totaled to just over R800. I tried to cancel my order and have my eBucks refunded, but could not do so. I called the call center and they cancelled my order. I planned on splitting up the order so that I could use all my eBucks. Now I have been told that my refund will not reflect immediately nor can they issue me with a voucher. This is pretty useless to me now as I wanted to purchase items via the daily deals! How is fair that I have to lose out on a deal due to your system not processing my refund efficiently? VERY DISAPPOINTING SERVICE!!!!
