Dissatisfied soon to be Ex-client

I've had an FNB account for several years now and ever since I upgraded my account to a premier account I've has ***** on my account and FNB have not been able to do anything about it. I've been getting monthly debits from "MZANSI" of about R 8.00 and I don't even know who these people are or what the debits are for. I also had a debit of R 117 from "REVOLVE" which was also un-authorized. I've called FNB regarding this and they've told me they can't reverse the debits as it is coming up as if it is their "fee", and they have obviously not stopped the transactions from going through monthly. The only thing they've ever done was to just send me a ***** form which requires me to go to the police station to open a case and requires a whole lot of admin on my part. I've already told them I did not authorize these debits, is that not enough for this bank??? How do they allow someone to debit your account if you did not authorize it, I don't understand. How is this bank protecting it's client when they can't even stop unauthorized debits after you Report the matter to them. Having been a client for so long and having all my accounts with them I honestly feel they could do better than this. I am now forced to move my accounts to another bank because I cannot deal with a bank that helps ********* to ***** money from their clients. It may be small amounts to them (FNB) but these small amounts debited from a whole lot of accounts, is a whole lot of money.
