My license renewal

Dear Sirs you sent me notification of my license renewal, which I did on 20 Oct 2017. Today you tell me my license has only 24 hours left to run. How can this be? Urgent advice please.

Thank you. What does one do to reach someone at Avast willing to answer my question. Having spent valuable time trying ALL the avenues, including Helpdesk, I cannot raise a single intelligable human response.
