Thank you for understanding.

I have been trying for days to figure out how to cancel a trial subscription to AVG Tuneup. Apparently, after today I am going to be billed $69.99. I CANNOT afford that. However, no matter where I go, I cannot figure out how to cancel it. There  is nothing showing under "subscriptions". 
I cannot locate anywhere to contact the company via a phone # either. This is the closest I gave come. Can someone please help me?
