Again a mess up on my credit card

<p>Once again fnb has messed up on my credit card account. Firstly they opened a premier credit card account when I app**** for a credit increase on my gold account, and while I was using the gold account, i was harassed for payment for overuse on the premier account for which no card was issued to me. Now after the limits where eventually 'fixed', and my new premier card issued to me, my first month end came. I made a R4500 payment into my premier account with the knowledge that it would cover my minimum installment due and leave me with an available amount for further purchases(online purchases and day to day groceries). Now after the 7th, apparently an installment of R4800 or some odd was actually due. This amount seems to be the total limit increase plus the minimum installment on a maxed out account. My expected minimum was in the region R800. Fnb is requesting a further R300 odd to re-estate my credit facility. But I have already paid all my accounts and all my remainder is lying in that credit value. I did it that way specifically to earn the so called e bucks. So now fnb has left me unable to buy bread, milk etc until the end of the month or until someone with a brain eventually sorts my accounts out for good. How can fnb play with people's lives like this. To worsen the situation, when i spoke to a consultant over the phone about this, she just hung up the phone on me. A complaint has at least been lodged with their admin department, but they clearly don't have the urgency to sort this problem out cause they really don't care about the problems they cause people.</p>
