FNB Suspends my account due to their negligence

I have an FNB credit and cheque card, and use both on a regular basis.<br> On the weekend I used my credit card on several occasions at multiple stores. All transactions went through and I however received no notification of the transactions via sms/ mail or internet.<br> 3 days later (today) all the transactions went off at the same time and my account went into negative and FNB suspended my account. After contacting FNB, I was told that the stores all banked the money late and it was not FNB's fault. <br> HOW COULD ALL THE STORES, ALL FROM DIFFERENT COMPANIES BANK THEIR MONEY ALL AT EXACTLY THE SAME TIME??? So, they suspended my account and I get a snotty message to say I will get my credit record negatively marked.... WHY?? Because FNB can't get the transactions to bank immediatley?<br> <br> Why is it that when I use my Credit card at other locations, the transaction goes through immediatley and there is no 'banking' required by the stores? It reflects in my account straight away!<br> FNB, I don't appreciate having my accounts suspended over your mistakes... please get your act together... your Credit Card service is not that great after all....
