This company is not to be trusted

I have app**** for a pension fund for my father who dead on 2019, in this company ,since I been communicating with them they have been asking money when ever I go to their office in Eldorado park . It's been years I been giving them money and yet they have not given me any cent . I wrote this review because I'm worried if they are legal or not because the money they have taken from me it's alot and I have lose the hope in that company even now they are saying i should send R 700 so that they can proceed my application. How much money will they take from us until they give us our money .
