paying admin fees for no reason

I need urgent help with sorting out my accounts. there is no use sending your aftercare an email cause they just ignore your emails. according to my records I have paid up more account then what you say I did. I have send numerous emails stating that my Nedbank account is up today and in a credit, requesting that you get that money and pay another account and to close my Nedbank account but nothing happens. last night I get sms's from RCS saying that they have not received any payment this month - WOW!! can someone please help me to sort out my accounts, can we please stop paying accounts that is paid in full and close them and distribute the money to the accounts left.
