FNB - BAD HANDLING OF OVERDUE ACCOUNTS - NO COMMUNICATION!!!

I have had countless issues with FNB and their handling of overdue accounts. The requested information is not given freely, in fact it is never given! I have requested initial default balances, i have requested statements and i have requested copies of the initial signed contract and received nothing. I have spent countless hours on the phone calling each department just to be put through to someone else who doesn't know whats going on. I am sick of the lack of competence shown by FNB and its staff. I was handed over for one account and was never informed of this, to my knowledge i had been paying FNB until a lawyer phoned me demanding collection fees! I would like FNB to live up to their legal requirements and send me the statements, balances and contracts i require. I have been paying FNB for 4 years and my balance has only increased - the In duplum rule applies to FNB whether they acknowledge it or not and i will not be taken for a ride by a greedy corporation. Had i not paid this account i would no longer be liable for it and FNB would have lost but all i have received for my willingness to pay is being taken for a ride and being overcharged ridiculously - i have been blacklisted by FNB and yet they are to receive more than double the amount owed to them
