Unauthorized debit order

In 2019 I was sold a drone by a sales representative which I did not get delivery thereof. On inquiring I was informed that my order had been canceled without any reason given, and that I will be refunded, which sadly took 6 months after countless phone calls. To my surprise now, on Saturday the 24th April 2021, my bank account was debited an amount of R908.00, which I know nothing of since I have never ordered anything from The Hobby Group since my last experience with them. On asking how this happened I was asked to forward a statement from my bank attesting to the debit order, in order for the "mistake" not to be repeated. I managed to reverse the debit order at a cost R45.00 bank fees. I am now waiting to hear whether the The Hobby Group will refund me the R45.00 bank fee.
