Terrible Communication & Refund Issues

I erroneously paid R1,000 into Buffalo's account when making payments on 28 February 2023. I immediately called and was emailed a refund form which I was asked to send back together with the proof of payment to Artie Ndabeni which I did. To date, despite a request for an update, I have not received one single communication from Artie. Buffalo, can I have an update and can you please refund my money, it does not belong to you!!!
