Missing Money in account

<p>i'm writing to express my frustration with FNB on how they are continuosly taking money out of my account with a valid explanation. I started monitoring my account online closely after i got a negative balance on my account. </p> <p>I noticed that my balance was always more than the available balance and I dismissed concern there as I be**** that this was because all reserved transaction were all under balance which was money I could not access. that was fine with me until when I realised that the bank was deducting money directly from my account and my account was suddnly -100. on asking for an explanation and a request for them to reverse the charge, I thought they would act on it quickly. It has been more than 48hours and noone has been in touch with me to rectify this and explain where the extra R206.98 that was under balance was for and is allocated to. Please help as I am really frustrated and feel like someone is eating from my account and the bank is being dismissive.</p>
