Easton Berry refusing to pay me my money

Easton- Berry owe me an amount of R6 080 (which is a refund for an account which was overpaid). I sent an email on the 9th of June requesting this refund. I received a response from EB on the 11th of June requesting for proof of the payments which I sent to them on the same day. At that time I was assured the refund would take a maximum of 14 days. 19 days later (excluding weekends and the June 16 public holiday) I have still not received my money. Since the 11th I have had no communication from the company. I have sent two emails asking for progress on the refund and have received no reply. I have called them 4 times and each time their admin staff tell me all documents are with their finance department and that there is nothing further they can do. On two occasions (after I’d called to enquire) I was promised the funds had been released and that they would clear over the weekend. My last call to EB was on Friday, 9th July, where I was told by the admin staff and her supervisor that they did not know what was happening with refunds since their finance team is working from home. It is almost a month since my initial contact with EB and I am still waiting for my refund. The company has made no attempt to communicate with me about the status of my refund and every time I have reached out I have either received no answer or empty promises.
