Disappointed with B3

I am writing to formally lodge a complaint regarding my funeral policy with B3 Insurance, which is over 24 years. Over the months, I have observed several changes concerning your operations, including shifts in underwriters. And I have been getting different Pay@ numbers as they were changing underwriters. Now I have received an SMS stating that my policy is in arrears and I don’t understand how as I pay every month without fail. I am deeply troubled by the recent handling of my policy.
