Money taken out of my account by fnb without my consent

Dear Fnb "how can we help you?" Well It should be " Im sorry, but there is nothing we can do to help you!

All my Money went missing out of my account and thats the response I got; from FnB branch manager at Umgeni, Intersite avenue today. Here's the thing I find so Apauling , well there's a number of things actually. 1. My account was accessed by a guy named Graham from FNB or RMB. FNB did not notify me that they are accessing my account. No SMS . NO EMAIL. NO PHONE CALL. 2. All my funds were moved but there is NO Notification of the transaction. 3. Your notes say sars recalled the funds . SARS has provided proof that they have not recalled or placed a pledge on my account and deny any involvement. FNB notes do not have any reference numbers or case numbers and there is also no supporting documents attached to support the claim that Sars is responsible .The manager doesnt have authority to reverse FNB's error so he cant help me abd in the meantime i have no access to my funds. So there is no privacy or security with regards to our bank accounts with FNB and they falsely advertise because they really can't help us. Pls tell me who is going to provide my childrens basic needs if i can't access my money that you have mis-placed and you cant help me.
