ROYALMARK (theft) debit order at Cepitec Bank

I am extremely dissatisfied and distrustful of Capitec Bank. Someone by the name of ROYALMARK did a debit order of R115 on my account (with out my knowledge). I have reversed and blocked the debit order, yet it still goes through. Is this bank even interested in investigating the matter? As I might not be the only one. Is this bank even concerned about the keeping our finances safe at all? This is not the first incident where I feel unsafe about money, and Capitec does not seem bothered.
