Standardbank recoveries department incompetance

I phoned Standard bank recoveries department on the 17th December 2014 and ask for a settlement amount with a discount (because I am settling the account sooner). They gave me the amount I needed to pay, I paid them on the 17th December 2014 as they requested immediately. THE SAME DAY!<br> <br> Up to date (02-02-2015) I have NOT receive any communication or a letter stating that I have settled the account IN FULL. They are keeping me hostage by not issuing the closed account letter. I have NEVER defaulted on any payment made to this account. Quality living have been sending them emails after emails with NO response from them.
