hi 

how do I contact AVG, I received an email saying that I'm going to be charged £29.99 as my free trial is coming to an end, however I did not set up a free trial as I already have a AVG VPN Subscription.
I really don't want to be charged £29.99 for something I'm not using or haven't set up.
Thanks 
Mary
