Delaying refund

I ordered 68 bedside lamps and 18 shower curtains at the Clearwater branch. I dealt with Simon. Firstly it was a mission to just place the order. No feedback was give and I had to phone after them constantly. After a couple of days I eventually received an invoice which I've paid promptly. Upon follow up (again from my side) we were told that we can only place orders if the amount exceeds R5000. My invoice was in excess of R14 000. After this was explained to them they then proceed to inform me that the items was discontinued. Why send me an invoice then? I then requested a refund from Cindy Moeng who sent me the invoice on which I got no reply. I followed up again and cc's customer service from Game head office in on which I got a generic response informing me they receive the query and will be in contact shortly. I sent a follow up email again and needless to say, I'm still waiting. Is Game doing this on purpose to draw interest on refunds due to customers? Poor, poor service. It's a pity that bad service is becoming more and more acceptable in South Africa. It's almost as if the businesses feel they are doing their customers a favour by delivering a service. Game used to be a decent store. Now it's just a glorified ****a shop
