No a happy client

I lost my 6 month old son on the 6th June and he was only 6 months and a week, I have a policy at capitec of which I pay every month, but when I went to make a claim they declined my claim they told me the child was already 6 months and 5 days old so they can't help me, my son would be turning 7 months only on the 29th of June, I really had difficulties burying my son due to financial constraints so I would like to know if the child has passed on at 6 months and 5 days does it mean my claim is not valid, what is worse is that the agent refused to send the documents saying they will reject the claim
