Charged for unauthorized Debit orders

Unauthorized debit orders are going through my account and i am being charged for them. i called the call center to complain, they were reversed but i was told to go to a branch to reverse the 'unpaid service fee' that was charged because the unauthourised debit order did not go through due to insufficient funds in my account. So now i must drive to the nearest branch monthly to sort out this since the bank in unable to protect us from ********?? please the R60 unpaid item fee that was charged on my account on the 31st March 2018.. i dont know who this people are and pleas block them as well.(AEDO REPRESENTATION ZWELOS DIR ********** 0 SAGE180329 R 88.00-)
