Can't access my own money!

Yesterday, I transferred most of my salary towards paying my credit card. Unfortunately, s#@^ hit the fan and I needed to use that money and the payments MUST be made to my cheque account. So, like I have done countless times, I transfer all the money back to my cheque account. But then, the money is not reflecting. So now I have no money in my credit card and no money in my cheque card and I need to make an immediately payment. I call FNB and I'm told the money is "being processed". What new ******* is that? and then I log a call and I'm told it will be done in maybe 2 hours. Great, so I must tell these fellows who are waiting for their money that they will get it in 2 hours. This is utter *******. My money is essentially being withheld from me. I wasn't even making an external payment, I'm literally transferring money between MY OWN ACCOUNTS!! So disgusted with FNB right now and the service I got. Get rid of the banking app if it is just going to ***** us over
