Extremely dissatisfied and horrified customer

It is incredibly disappointing that this is the only route I can go down to get assistance from FNB. I have contacted the Revolving facility department to no avail, I have contacted FRB Debt Review center to no avail absolutely no one has been able to help me and sort out this very easy procedure for settling and closing my revolving loan facility, in three weeks, the money is there its all paid and yet. Neither the revolving facility or debt department have contacted me to sort this out. I don't think they actually understand the word customer service, and I am sure I will probably wait until there is another bank charge to come off and I will have to pay that, so fantastic they are taking more of the money that I have now paid twice while they don't fix this problem. There is absolutely no way in hell I will pay another cent to them. There is no need for another customer care person to call me as that has been a waste of my time and energy as it has not helped and they always say it will be sorted and yet 3 weeks later that is not the situation. The worst thing is I actually have no idea what more to do, I call everyone, I email everyone, I go into the bank and no help, all just to click a button on their side. I am now with a new bank and when I paid my loan at that bank it was cleared and sorted that day, all I want to do is be free of all of this and finally close my FNB account, will be the best day ever. Something they obviously don't understand and have no heart or care, that it has been a difficult ride and to finally be able to pay off my huge debt is a massive weight off my shoulders, YET I cant seem to do that.
