Live support is available from 9 AM to 5 PM EST, Monday through Friday... as well as whenever the support team sneaks in on nights and weekends.
You can email us at support@guildlaunch.com - if you have a billing concern, make sure to send us an email.
If it's something the community can help with (which they usually can - they're awesome), post here in the Support Forums.
You should also check out Uservoice for our FAQ, Feature Requests area and Game Requests area. It also has a ticket system where you can contact us directly.
