FNB doesnt know their own systems

I have an FNB credit card.<br> When I took out the credit card I put a large sum of money into my credit card for the finishes and extra's for the house we building.<br> I made a purchase on my credit card but put it on budget as I needed the other money for the house.<br> The very first time I phone FNB premier banking they told me that due to the fact that my straight on my credit card is in positive my budget repayment will be taken from there.<br> When the positive balance on my credit card was used up for the house stuff I phoned FNB premier again to ask them how will it work now, the lady I spoke to told me that I can use the option on my Online account to pay the funds into my budget which I done. Then on the 8th of this month when I logged into my online account I saw my credit card was again in negative. I then email my premier banker and ask him to arrange a reversal of the other amount taken from my straight, after emailing him the whole time which he never comes back to me I finally received this reply. \credit card department have confirmed that they are unable to process payments paid into the budget facility. I cant accept this
