Unfair:I just service by OMG

I am treated unfairly and seek justice/ help from Hellopeter. I have been having a comprehensive + family funeral plan with old mutual for more than 10 years, when my marital status changed from married to divorced, I went to the nearest branch then to update my profile /account. I kept paying the policy premiums regularly as stipulated, monthly, as the man is the father of my children. He passed on on the 31/7/2021, when I submitted claim I was told then that I cannot be paid because on their system the deceased married someone and I should have mentioned that it is ex spouse. My question is what difference does it make , in my own understanding I updated tgem that the man I marrried is no longer my husband, we are divorced. I feel very disappointed and dissatisfied because I updated my profile on old mutual system when the deceased married someone, nearly 5 years ago, and I have been paying my premiums ever since the inception of the policy( old mutual group scheme policy number: 69253N***
