Financial safty at risk

I have been with Standard bank for for more than 10 years now, for the past tree years I have been battling with unauthorised debits, I am aware that the bank is aware of the matter but I am still billed for both the debit and the reversal, which I find it unfair since we use banks to protect our finances, which today are no longer protected. I believe we are used by the banks for by the banks for billing us for what we do not know. The bank and the goverment are aware of the problem but the bank gains while clients lose, emagine how much have I lost in 3 years and 3 debits a month? This needs proper investigation by the state as well.
