Refund never paid for "out of stock" items

I ordered and paid in full for an item (order#***) on 11th Oct. I received an email from Karibaa on the 12th Oct informing me that the item is out of stock and would receive a refund within 7 working days.. I immediately provided my requested bank details and have still received NO refund after multiple requests. They do sometimes respond by saying the request has been escalated,, but then nothing. I have informed Karibaa that I will file a a charge of theft/***** against them with the SA Police Service if they do not refund the amount in full. Unfortunately still no response. These are the facts and have all of the communications to prove their irregular business practices.
