FNB debited my account without my authorization

I am very disgusted by FNB. This morning they debited R2000 from my account without my concern then I went to the Melrose arch branch to get more clarity on this unfortunately no one was willing to give me a straight answer instead I have been sent from pillar to post and the consultant I was dealing with is Lufuno Mashavhanduna.<br> Instead the consultant just gave me a number that keeps on ringing and say there is nothing else she can do. I really feel FNB has invaded my privacy and violated my rights as their customer. I mean i have trust them to look after my money yet their are the ones who take my whole R2000 without my concern/autorization. THIS TOTALLY bad service from FNB.
