Ignoring all communication. With no communication.

So I've been attempting to get in touch with Momentum in order for me to claim my Provident fund. I've sent emails on: 19/10/2018; 20/10/2018; 22/11/2018; 28/11/2018 and again today. The last email today was sent after attempting to speak a person there on the telephone, after holding for approximately 30 min, while holding you are reminded constantly you can leave a voice mail, so eventually I decided to leave a voice mail, guess what the mail box is full. I contacted this number: *** So now I would like to know, in more than two (2) months no one has contacted me at all. Even though a automated email reply is sent, stating it will take 26 days for a reply from them. at the moment it might 260 days. And all I want to know is how to go about claiming my funds. I find it very unprofessional and completely infuriating. I understand they are busy, I understand they have millions of customers, complaints etc to deal with on a daily basis, but surely someone can just reply to my correspondence saying, we are busy with you request or just reply to my mail explaining the process to me or even just forward the documents to me to claim, please can someone just contact me. I've supp**** a reverence number as well as my ID number.
