ABSA Unauthorised debits on my account....they cant do anything with it

A very impatient and no-help-at-all provided Nthabiseng called me. She tells me to go to the branch, which i told her i did before and this did not help. She says i must go again, to which i ask what will be different this time, especially the outcome as i went and these debit orders still carries on. She tells me she will send me a letter stating that i should go to the branch and dispute, which i asked her to include there what happens after that process and the same still happens. She refused, saying she cant talk about things that she doesnt know will happen. I told her it will happen because it shows on the history that from around April, these debit orders has been running, and there is nothing they are doing about it........Im shocked to the core. This is an institution we trust with our money. She says there is no verification when a THIRD PARTY comes to their account, to claim my money. They dont have to check if i granted that permission, THEY JUST ALLOW ******* INTO MY ACCOUNT, THEIR ACCOUNT. Nthabiseng as i kept asking questions, said CAN I PLEASE DROP THIS CALL, THERE IS NOTHING FURTHER I CAN HELP YOU WITH. I want to puke right now, when i go to the branch, i will be going to close the account.
