PROVIDENT FUND WITHDRAWAL NIGHTMARE!

I have been waiting for Liberty life to finish processing my provident fund withdrawal since June. First I waited for weeks before I was told that they were waiting for SARS to confirm my tax number. Monday when I phoned again I was told that each time my policy number is put into their SARS tax directive the system trips. I have given up on this policy in 2005 as well because there simply seemed to be no progress with processing. What gets to me even worse is that I was told the money would be in my account in fifteen days, but it has now been three months. What more should one do to get what's theirs at Liberty Life? Also, the amount mentioned to me by a consultant seemed to be ten thousand less than what my policy is worth as per Sanlam, the initial company I had the provident fund policy with. I'm fed up with Liberty Life and need nothing else from them but my money!
