Terrible service

Wow what a hustle to get a response from these ppl, they don't even deserve a 1 star in my opinion, So the last past months I've been trying to get a response from them regarding my withdrawal, no response from them instead I'm the one who's been calling and I have been getting the same response the person who's handling ur case was on leave... Or she's back and swamped like what is happening? So I used to work for Edcon and since Edcon is no more my understanding from the last consultant I spoke to is that my provident fund was moved to my current employer, however there is a potion of my investment from another company( old mutual) that I used to invest in thats the potion I would like to withdraw from, but since I've been waiting from a response from Portia whose on leave and since she's been on leave nothing can be done...ridiculous for such a big organization
