Bad Pension Fund Administrator

There is a lady named Banele Dingiso who has been dealing with my Fathers pension fund pay-out. It came to our attention that the pay-out was missing a huge sum of money and upon investigating the missing money it was said my Father had taken out a Pension Backed loan with Standard Bank and SALA. Now, he was paying back that loan until it was moved over to another bank (FNB) and he continued paying the new bank too. Now, it was said he defaulted on payments which upon thorough investigation it was proved that he did not default. We have submitted all necessary documentation to prove that he has been paying and the documents also include "PAID UP LETTERS" from both Standard Bank and FNB. Now, Banele is ignoring our emails and not responding accordingly as agreed when she said we must said the documents. Fairsure seems to be siphoning money from unsuspecting people (my Father) and refuse to perform the necessary steps to investigate and payback the money as it warrants.
