No response from 1Life

I sent an email to 1Life asking for the details to pay off an outstanding premium and to date I have had no response. The email was sent to complaint, customer service and info. Is this company still existing? There is an amount that is outstanding on my husband's premium, and I am paying the premium and I need to bring it up to date. I even tried to cancel but they would not allow me for some reason. Please could someone urgently assist me. thanking you
