Refusal of Refund

My company ordered protective clothing in June 2020. On several occasions we were told the disposal suits were not available when we wanted to collect the PPE. I contacted the branch in Montaque Gardens in August requesting a refund as they were not going to get the stock. I was contacted by one of the Sales People and promised the refund. I had to phone in the branch several times stating the Head Office was relocating and that I must please be patient. In September when I contacted them again, I was told I have to provide proof of banking details, which I sent to them immediately. To date, I have not received my money back. There is no way of contacting the Head Office as the only numbers on the website is the Cape Town Branch. I even went as far as pleading my case on the website, hoping to get Head Office to see my request for refund. To date, I did not get any response. I got the number for the CFO and the call goes unanswered. All I want is the refund for the money paid as I did not receive the PPE. This is not an unreasonable request and I am finding it difficult to understand how a company that size does not have alternate numbers to contact their Head Office.
