Sanlam Administrators never go through claim documents customers email to them.

Have been going through reviews here and i have come to a conclusion that Sanlam is not a good company and nothing know about customer service. It does not look like their fund administrators even go through documents that are presented or emailed. The only thing they are good at is hide behing the call centre agent who can only escalate and nothing ever gets resolved. Submitted my dad's claim who passed away in 2008, its an unclaimed benefit, they came back asked for the affidavit which was provided for about three months ago and to this day they either ask for that affidavit or a marriage certificate which we are unable to provide because he was never married and his death certificate states "never married". Its seems like they are looking for every reason not to pay what is dues to its customers whilst they get their salaries every month and the most frustrating part is you never get a to speak to the so called administrators or person responsible for the claim and if you lucky even to get the landline for the so called administrator the phone never get answered. What is one supposed to do now?
