Long outstanding refund

I purchased a few items from spree.co.za on 17 October 2017, some of these items were returned on 24 October 2017, since then, I have made several phone calls and sent emails indicating that I have not received any refund as yet. I was told by a call centre operator to check my bank statement, as the refund may have been offset against the original purchase amount. This was not the case, the full purchase amount reflects on my statement. I was told to provide bank statements, which I did. No response received from them and once again I had to call them. My last call was during the week ending 10 November 2017 and they indicated that they would provide me with proof of refund on Friday 10 November 2017. I To date, I have received no such email. Also, as of today, 12 November 2017, no refund from spree.co.za reflects in my account. Surely a refund does not take this long, also, if spree.co.za is are reconciling accounts, they should have detected this. Makes one wonder what the person processing account refunds has done with the funds, sounds very fishy. The refund number is ********** 12-1.
