1LIFE NO RESPONSE

I KEEP ON SENDING EMAILS TO CANCEL MY HUSBANDS 1LIFE POLICY. WE REVERSED THE PAYMENT AND THEY SENT AN SMS ASK IF CONSULTANT CAN CONTACT HIM REGARDING PAYMENT, NO PHONE CALL ITS BEEN TWO WEEKS. AND WHEN I PHONED THEY GAVE ME A DIFFERENT EMAIL ADDRESS BUT IT DOES SHOW THAT EMAIL ADDRESS ON THEIR SITE OR DOCUMENTATION. HOW CAN WE GO TO HAVE IT CANCELED FROM 01/10/2018 AFTER OUR NEW POLICY STARTED MIDDLE SEPTEMBER.
