Freezing account without valid reason

I'm always saying how good FNB is and how happy I am with them, but today was a shock.<br> <br> 2 Months ago I received a letter stating FNB needs my proof of residence for some FICA thing, apparently the Statements they send me don't count, so I sent some other documentation to them, to which I received a reply stating all in order, thank you.<br> <br> Today they decided to Freeze my accounts as the documents are not correct, I mean come on, contact the client first and explain the situation before taking action, so today I went to my supplier to purchase stock and I look like a Fool as my card is declined, not very impressed.<br> <br> So now I'm stuck with no access to my money, and no one can assist till Monday, THANKS FNB!!!!<br> <br> FNB let me down badly today, I will be thinking of moving banks.
