Online order cancelled and money not refunded

I placed and paid for an order on 12 Sep 2023. The following day, I was informed that they did not have the product. I agreed that I would accept a refund and didn't have a problem with that. I provided my banking details for the refund and did not hear back from them. I followed up 2 days later and heard nothing back from them. I decided to give them additional time for the money to be paid back. More than 2 weeks later, multiple phone calls and emails, and they have not paid me back and do not communicate with me. They stole my money. DO NOT BUY FROM THEIR ONLINE STORE!!!
