Changing an advertiser's group that belongs to a reseller
Your resellers don't have the option to change their advertisers' groups. As an admin, you will need to go to your administrator dashboard and under "Advertisers" click on "Manage." Next, search for the advertiser that needs the group change. Once you find your desired advertiser, click on the package link. Choose the group you'd like to assign and click "Apply" for the changes to take place. Only the features of the selected group will be displayed to the advertiser.
Have a great week!
