FNB wrongly deducts & refuse to reverse

<p>My bank FNB, deducted more than they are supposed to as per contract signed with them. This is the second month and they kept promising to call me back in September and nobody did. They did the same thing again in October where it was even 4 times the agreed amount. When I call them they acknowledge that it's their fault but they inform me that there is nothing they can do about it???? Private Banker has no help I am being sent from pillar to post. I need the money, it's a tough economy out there.. PLEASE HELP URGENTLY!!!!</p>
