Order *** – Xbox returned, received but still no refund after days (not as described)

I bought an Xbox Series S online from the Craighall Park branch (order ***). The listing clearly said “Storage is 1TB” and included 1x power cable. I received a 512GB model with a faulty controller and zero cables. I returned it via courier last week. Craighall Park confirmed they received it, and I provided my full bank details (Standard Bank) for the refund. I have emailed multiple times (including customer care) asking for a timeline, but received no proper reply. This is a clear 6-month guarantee claim for an item “not as described”. Under the Consumer Protection Act they must refund the full R5,748. The lack of communication has caused unnecessary stress and wasted a lot of my time. I just want my money back as soon as possible
