Greatly disappointed in the poor service from Capitec Bank

I had a Debicheck payment that went off my account without my authorisation. I contacted Capitec bank and they advised me that there is nothing they could do for me and I need to get hold of the company who loaded the debicheck. The number Capitec supp**** me for this institution who debited my account, was a number for a complete different company who did not have any details if me on their system. I got an affidavit from the Police Station, and went in to the branch hoping they would be able to reverse this transaction. With great disappointment, the Capitec consultant who "helped" me, ultimately advised me that there was nothing she could further assist me with, and the best alternative option I have is to open a new account (which just defeats the purpose as this debicheck can clearly be loaded on any Capitec account without authorisation of the account holder), and I couldn't open a new Capitec account anyway as this current account is still active. So she did not help me at all. I then suggested that I will move my available funds to another bank, and then close my Capitec account (as there is clearly a security concern), and the consulted just shrugged her shoulders and said "That might be the only alternative option". I am greatly disappointed in the poor service received from Capitec (Not to mention the funds that I have lost due to this transaction).
