Can't contact support

I’ve been trying to contact support but I can’t, I need to cancel a subscription but I can’t because I made a mistake when I wrote the email adress assigned to the account of the payment, and now I can’t access my account and cancel the subscription

get a hold of them through either facebook messenger or X to get a hold of an actual person

If you made the subscription via Google play store just login to your Google account and cancel the subscription I’m not sure about AVG but with some subscriptions you can get a refund for any unused periods of the agreed subscription term. Hope this helps.
