Provident fund claim unpaid for over a year

In March 2019, the company I was previously employed in submitted the paperwork for my provident fund claim with Sanlam, after 3 months I received a call from one of Sanlam claim agent by the name of Thabisile who informed me that SARS was rejecting my tax number so I called SARS to find out of there was any issue, they informed me that thwre is no issues and nothing to fix, after three months I received another call from Wandile who is also a administrator claim and no help, till today 30th October 2020, I have never received my provident fund claim.
