Disappointed customer

I had a funeral policy with Old Mutual for my dad. When my dad passed, I was told the policy lapsed and I was not informed. No reasons were provided. I had another policy for my son. Apparently, I am now told it lapsed. My other policy for myself, the cover amount on the statement says R100k and on the schedule is R10k. Can Old Mutual please be fair to its customers. I trusted them with my money, but all these made me move to another bank.
