No goods, no refund

We placed an order with Essops for some furniture on 8 June 2020 online and paid via credit card. On 11 June we were informed that the item we ordered was no longer available and so we requested a refund. We have been speaking to Kim and Ayesha for 2 months now and every time we are told that the refund has "been submitted for processing" We have still not received our refund and lately our mails have gone unanswered and Ayesha, the manager, is never available and does not return any calls. I certainly would advise against purchasing anything from these guys
