Very disappointed in hollard

I told a hollard policy for my uncle on the 27th Jan 2021 in a pick n pay with a consultant representing hollard and I was made to make the 1st payment in store which I swopped my card for the 1st payment on that day and hollard started to debit me from 2nd march 2021 and my uncle pass on the 20th July 2021 which is after the 6th payment of the policy and now when I submit the claim it's declined and they telling me he did reach 6 months so I asked Roger Stenele who called from claims department how possible is that because he passed away after 6 payments which is 6 months waiting period and he said no that's not how it works only if he passed on after August payment he was gonna qualify which that was gonna make month 7 now I'm confused I need clearity or maybe I don't know how to count. My claim ref CLM***6 and my contact details ***
