Unauthorised Deductions by Busbur Pty Ltd

I noticed monthly amounts being deducted (R95) and contacted my bank. They advised it was by Busbur Pty Ltd (Barend Du Toit), a company/individual that I do not know nor have dealings with. I tried calling him on the number the bank supp**** but of course the number was not answered. The bank said it could be an add on via a mobile network subscription but could not confirm. Can anyone shed any light on who the hell this guy is and how i get my money back ? I have stopped the debit order with my bank. Based on other's experiences seems this is happening to many others with the same frustration.
