Old Mutual Superfund dragging their feet on a Death Claim

My Late wife was a member of Old Mutual Super fund. She passed away on 25 July 2021. I, with the assistance of her employer submitted all the necessary document within I week of her passing. All the documentation has been received by Old Mutual Superfund. Option form. Proof of Banking details. They have had the final documents for 3 weeks. All the administrator needs to do is submit claim to SARS for directive. SARS gives a directive within two days. The administrators still have not done this. The staff at the call centre are very helpful and try their best to give us all the information they are able too. However the administrators do not even react to their requests to contact me. It is just ignored. This is so unprofessional. One likens them to Government Departments like home affairs. We, the claimants need answers. In my case I am warding off claims from the various medical institutions that treated my wife and because of a shortfall on medical aid cover, monies are owing. I am also a pensioner and do not have funds to cover these outstanding amounts .
