Very angry and disappointed customer

I had a credit life insurance with Yalu I switched from African Bank.They got liquidated and now Meerkat took over I informed them that the company I work for got liquidated and sent through all relevant documents. Now that its time to settle my account with african bank I am told that my policy has lapsed due to nonpayment of premiums. Yalu had a catch all benefit where they will cover u for what ur current credit life covered u on. Now African bank doesn't take premiums when you are unemployed. I want to knw why is my acciunt not settled
