Rude and pathetic service!!!

Their service is pathetic!!!! Ive been struggling to get my funds from them for the last 5years i told them several times that the employed no longer exist and i moved jobs but yet they still want a signed form from the company that is no longer here like really ***???? I dont understand its money i contributed from my salary and they are fighting me to keep it and not give it to me. I called in again a week ago after making several calls for i dont know how many years to submit my claim sent a email telling them the story them up till today i still didnt get any feedback as was promised by nolwhazi mabena then when i called in and got hold of her she told me oh no i was on sick leave like really u have the audacity to tell me youwere on sick leave so no one else could assist me??? I feel that they just dont give a fock about you i called in today and i asked to speak to a manager the agent hilton was so rude and transferred me to someone else i feel like everyone that assisted me needs to be fired especially hilton he was so rude and shouting at me i feel like im getting no where with this !!!
