Not happy with 1Life service and left hanging

My younger brother by the name Anele Smith had a funeral policy with 1life for a very long time and it was deducting on my bank account and I only noticed this year 2023 that this policy is nolonger debiting, I made a follow up with 1Life and to my suprise they say my brother cancelled the policy last year, I asked my brother he said he doesnt know anything about policy cancellation as he solely depends on that policy for anything thay might happen on his life and sadly my brother got ill before we could investigate more on the policy and was hospitalized for a month from End January to End February, I focused on his health and sadly he passed away on the 27th of March....

I prepared funeral and made sure he was buried in a dignified manner on the 2nd April, as I revert this week I feel 1Life did so sort of a ***** or non-compliance to my brothers policy and I want to escalate this matter as I am still left in the dark regarding this matter, my external family members have policies with 1Life but if this is how 1Life treats its clients then I am ready to campaign and diss this company,

I thank you
