Cannot get through to the Mineworkers Provident Fund to claim outstanding benefits.

I received an email from a ICTS tracing company a few months ago with regards to unpaid provident funds that are due to me, and I was told that I would be sent the applicable documents to claim within 2 days. To this day I still have not received anything, and when I tried to get hold of the company again, the email came back with an error message. I have tried to contact Mine Workers Provident Fund via various means but I could either not get through or emails were just not answered. I finally managed to find /www.mwpf.co.za and tried to submit a claim via their website, but the upload feature just hangs. I sent an email to the email address listed on the site, once again, no reply. I finally managed to get through to the number on their site after a few days of trying, just to be met with a person answering that could not give me any coherent information. I was given the email ********** to send an enquiry to, I am still waiting for a reply. Why is it so impossible to be able to claim funds that are supposedly due to me? I have looked on the system at the above given website, and it does state that there are outstanding monies, but I cannot get anyone to pay attention to my enquiries. Is there anyone that can help me in this regard?
