I will NEVER MAKE use of their services AGAIN.

I shopped online and app**** a discount voucher they gave me a discount of R600 on a order that came to R1700, which is the amount more or less I spend every single month at their online store, they then emailed me to say they made a mistake on their side (ON THEIR SIDE) and they gave me a R100 voucher for the inconvenience caused, a lousy R100 for a customer that spends a large amount EVERY SINGLE MONTH. They are due to refund me my monies I went and paid, I was told this morning I need to wait 24-48 hours for my refund voucher, after they made a mess of my order, I now need to wait even longer for the mess they made, I will NEVER MAKE use of their services AGAIN.
