Poor customer service

I purchased an item but upon delivery found that it was damaged. I immediately phoned the Wynberg branch where I purchased it, after she made me wait 10 min, I was told to send it back with the delivery guys. I was told she "will have to see if another one is available". Next day still heard nothing, no confirmation, no apology, nothing. When I asked for a refund I got told off very rudely that I must wait 7 days to be refunded! The manager doesn't take my calls. They were available when they took my money but now that I must be refunded no-one is available to help me.
