Demands renewal payment when payment has been collectected last month

Hello Robert,
We are sorry hear that you get expired message from AVG. It seems that the AVG program you have renewed is not yet activated in your computer .We suggest you to uninstall AVG Internet Security you have in your computer from control panel and install the latest version from this link http://files-download.avg.com/inst/mp/Internet_Security_1824.exe and activate the product using your AVG MyAccount credentials.
Thank you

I am constantly receiving notice boxes stating my security has expired although it was renewed automatically last month and paid for.
