Thank-you for the link. However, I already give this to many trying to unsubscribe already along with this one https://support.avast.com/article/Unsubscribe-FAQ/#pc
However the current support structure is a bit of a circular maze, why else are there many angry users unable to cancel and or get a refund.
This structure needs looking at so as it isn’t a circular maze with many users in this forum unable to unsubscribe..
As for possibly using a different email to subscribe then how would they be able to install and log on to on to their account
