Fnb and Clientele where is my money?

I have been struggling for the past 4 months to get some debit orders stopped and reversed. I have been sending numerous message to FNB via Cellphone Banking without any real help.. They direct me to use my cellphone app to stop the debit orders but it can not be done on the app, I went into the Silverton Branch and after 3 hours the guy who was supposed to help me did not have a clue to how to stop or revered the payments. I don't have any airtime left and I need this resolved by today... I don't even have bread in my house... Nothing and need this money to be paid back. Also I did ask if FNB can help me with the debit orders that did not go off on my account due to a lack of funds I cannot afford R110 on each debit order that fails. I did told the providers that they must not debit my account plus I have stopped most of the debit orders with said suppliers... But for instance Clientele just ignores my emails and if you contact them the suddenly have technical issues, this is a lot of BS!
