Unauthorized Debit Order

I`m being debited monthly for an amount of R99.99 by NTN Seniorbud and another R99.99 by Groupcolle whoever these people are. I've not given any of these guys permission to debit my account! I queried this with ABSA Bankand was told to call these guys myself as they can't do anything on their side! The question I have is that when a company attempts to load a debit order against any of ABSA's clients, does ABSA just load the debit order or do they ask for a proof of an agreement between the account holder and service provider? Can I have answers as to how these people can ***** my money with such ease and what action will the bank take once they establish that these debit orders are not legit. I want all the money these people stole from me and I'm wandering if it will be paid back to me with interest. This is happening for the second time now and am really disappointed in the security banks claim to offer over our monies.
