Mattress Warehouse Randburg won’t pay me back my refund

I would like to report a Katlego Shomang from the Mattress Warehouse in Randburg, I requested a refund for money I had paid to the Mattress Warehouse on 7 December, I have had to call every day to enquire how far they are to refunding me my money. He is very *********** As he had to be reminded and forwarded emails he had acknowledged as having received to date I still have not received my money back despite all documentation submitted that was requested.
