Just impossible to use AVG... 14 tabs open and going in circles. Just want to cancel everything. So fed up

I have an AVG account linked to a Gmal account and now duplicated under a yahoo account. Paid twice. I was trying to buy the tuneup product because Im so sick of the critical warnings AVG keeps sending me. I have ended up with two instances of internet security. Desperately trying to clean this up and its so frustrating. Unable to email support. Maybe this community forum can help
