Where is my refund???

Still waiting for a refund from the store after being sold the wring part. I have called in a number of time to find out when I will get my refund and the refund lady is nowhere to be found or I am connected to the guy who sold me the wrong part and said he would process my refund. I left my original receipts at the store on 1 August 2025 and emailed my bank statement and ID copy to Dinesh Rakesh Naikram who then sent me his number to whatsapp him the documents which I did not do cause his whatsapp is not a business tool. I called the store after and wasput through to him amd he confirmed that I will be getting a refund in 7days. Today is the 16th of August 2025 and I have not received anything. This os a small amount but it does not belong to Williams Hunt Fourways. Dont rob me
