Lack of Communication and Claims not being paid

We have submitted documents for our mother's death claim (provident and pension fund) since the 31st of July through Magalies Water and had to resubmit the documents as they were unclear on the 18th of August where by the 18th of September we had to submit our mother's ID copy but since than no one is giving any feedback and the claim has no yet been paid, it has been 10 months now the documents we have submitted are about to expire. ****a Senne is the one handling the claim but they are very silent and does not respond or give any feedback, we need the money urgently as we have children who she also supported to support them as well
