Not giving me my refund

I placed an online order with incredible connection and I have not been helped at all. I made a purchase 10 days ago which I was told could not be fulfilled due to lack of stock... Which was a lie as I went to the store myself and they had stock, which I had to pay AGAIN to purchase as it was a store order and the previous one was an online order. So now I have spent R8,000 in total on two of same item. My online refund I have been fighting for 10 days to get a refund and despite providing multiple bank account details no money has been received and no POP sent. I'm furious now and will be taking further action against this company for withholding my money.
