Old Mutual *****ing from pensioners and cancelling policies without any notice

Contacted OM somewhere in October 2020 to enquire what steps to follow in order submit documents for death claim. She asked for who and she was able to tell what and how to submit. Since then I have been trying to call, phones not answered, emails not responded to irrespective of how many follow ups. Even contacted the PO of the fund to no avail. His pension monthly pay out stopped in October already before they could receive the necessary documents. Now in March finally got assisted only to be told that 2 out of the 3 policies that my dad had with OM have been cancelled. My mum will continue getting monthly payment from this one annuity policy that's paying the smallest monthly pension. No information about the other 2 at all. It is just cancelled. My dad was a proud employee of OM and I defended it when people spoke ill of it. I have a RA which I'm positive I'm taking it somewhere else. It is so obvious that my children will suffer if I am to die anytime. OM doesn't care about us their clients, only care about their bottom line. This is actually *****ing. My poor 76 year old mum, have to suffer. They don't even deserve a star at all
