Pay back the money

I over paid my account and I have been struggling to get my refund or any feedback from Total Sports. I informed the manager at Table Bay Mall in Bloubergstrand and was advised that I need to provide proof of payment, I did this and was told that the money would be in my account no longer than 15 working days, it has been quite a while now and I haven't received concrete feedback regarding the matter. I subsequently went to the store again to confirm the status of the refund and was told that the only feedback they have for me is that someone spoke to accounts on the 23rd of February 2018. I would like someone to give me a concrete answer and advise on the current status of my refund as it is in excess of R5000, you know basic answers ie is the money going to be paid, when is it going to be paid, those answers would give me a great deal of satisfaction.

Awaiting your response, patiently...
