Bad service

I called Hammond Pole Inc on the 21 September 2015 to request settlement amount on two of my African Bank accounts. They gave two settlement letters that included settlements amount and said I have till the 29 September 2015 to settle these account. I paid full amounts stipulated on those letters settlement letters on the 23 September 2015 and faxed pop to *** as per those letters. They confirmed that they have received my payments. Now I'm struggling to get letters confirming that my accounts have been paid in full and is closed. Spoke to Supervisor Thabang Maponya who was very rude and ***********, he told me I must pay collection fees, spoke to him more than 10 times via email, all along never said anything about collection fees only today he tells me about it, spoke to several consultants but no help even spoke to manager Bheki Chiloane said will call me back in 15 minutes time but never returned my call.
