Ordered Products, nothing delivered and no refund paid - Disgusting service

I placed an order with Spree.co.za on the 21st September 2017 and paid for delivery for the following day. I tracked my order the following day only to find out it had been cancelled. I immediately phoned Spree only to be told the order was cancelled because they didnt receive payment, however I got a notification that the payment was made and the deduction reflected on my bank statement. I was told to contact FNB to ask for a reversal which I did, FNB asked for an email from Spree with all the details in order to attend to the reversal. I spoke to a consultant at Spree who said he would send the email immediately. I followed up with Spree on the 27th September to see if the email had been sent only to find out it hadn't been sent to FNB. After being told by another consultant to phone FNB again because they would now be able to see that the payment hadn't been processed and they could do the reversal because there is nothing more Spree could do for me, I phoned FNB and was told that Spree had processed the payment and banked it in the 23rd September. FNB assured me that Spree had received the payment and needed to refund me. I then phoned Spree again and spoke to a very helpful consultant who spoke to the finance department and managed to trace my payment. Spree then advised they would process the refund and I was given a reference number. I followed up with Spree on the 6th October and was told that the consultant forgot to send the refund to the refunds department and was assured this would be done immediately. I followed up on the 19th October as I have still not received my refund, they told me the refund was paid on the 6th October. I am absolutely fuming as the money is still not reflecting in my account and don't even know what to do anymore. I find it absolutely disgusting that they still have my money and I have had to follow up this many times.
