Hi
Purchased 2 weeks ago VPN thru G2A and can not activate the program because after inserting the code, your webpage says that my activation code is already in use. Now seller want that I give them proof of used date of the code and says that I can get this information from AVG support. I tried to find an e-mail address of your support so that I can send you a code, but could not find. And also I rather not to share code here as this is an open community forum.
