How to transfer AVG subscriptions from one account to another


Hello. I'm having trouble with my AVG subscriptions. I accidentally used an email that I don't have access to while purchasing AVG Antivirus and AVG Tune-Up. Now that I want to cancel the subscriptions I cannot do it. I have logged into my main account on my AVG software on desktop and there it shows my subscriptions but when I open that account on the browser I don't see any subscriptions. Is it because I used a different email address while purchasing these subscriptions? The problem is I don't have access to that email and I'm not able to access my subscriptions. How do I transfer those subscriptions to my main account which I have access to? Please Help.
