Cancelling a trial for AVG Driver Updater

Hi. I need to cancel a subscription for a trial for AVG Driver Updater but
all the support page tells me is to log into my account and to it from there.

I didn't have a mail registered at the time of purchase - as I subscribed straight from the app - and, after registering one, the
subscriptions didn't not show up on my page so I can't deactivate any of them.

How do I make it so that the subscriptions I signed up for via the app itself can be registered in the new mail account I signed up?

Or is there a mail address I can send my request to unsubscribe to?
