First National Bank unexplainable charges

Fnb has been excessively charging me without any explanation and without reflecting this on my bank statement. Last month Fnb charged me something close to a R1000 on fees on my cheque account because FnB paid debit orders on my cheque account when there was no money and then charged me fees for that. I did not consent to that and I expect Fnb to merely inform the debit orders that the funds are unavailable as I do not have an overdraft facility and I have an arrangement with those debit orders to charge me on a certain date. Money also disappears overnight with Fnb and now I am forced to withdraw my money because if I leave any money in my account R200/R300 disappears daily without any explanation.

I want my money back because this is just unacceptable. You lie about the bundle you offer and you do something else. I do want my money back or I will escalate this to the Ombudsman. This is just *******.
