Not reversing faulty debit orders

Really disappointed. Money is deducted a couple a times a month,I contact FNB and was told that you do not do reversals anymore and that I should contact my service provider(which i did) I am suppose to trust you with my finances,yet you allow to take money out of my account without my permission and then you tell me that you dont do removals anymore,in a time like this! Is it okay to take a pensioners money? I will be risking my life next week going in to one of your branches to close my account and taking my money to another bank who cares about customers.
