FNB IS A *******

Good day

i have a FNB Premier account i pay just over R200 a month for no service i wanted to close my credit card account today my balance is R171.00 i asked for a settlement the settlement amount is Double R341.00 Please explain to me how the hell is this possible i will pay my R171.00 and not use the account if FNB Bills me then i will not pay it as this is not explainable the consultant i spoke to does not even know what she is doing as she had to put me on hold to ask another consultant for help,

im just awaiting that my debit orders go of then i will cancel my account and go to Capitec as they have almost no fees
