Unauthorised Debit orders

I have 2 unauthorised debit orders, the first one was from DoubleJCE for R89.00 and the second one was from Value added rewards for R125.60. I don't know who are they and where they received my banking details from. I tried to contact the numbers on the sms and they don't exist. mind due I'm being charged for reversal. Viceroy has labeled Capitec as a loan shark is this the way of making money on your side through unauthorised debit orders ?
