I apologize you were not able to get in touch with our Support teams this past weekend. While our phone support is not available, we do have limited Support resources available (Sat & Sun). This help would be through Twitter and here in our Community. As for being able to add in your contacts, did you receive any error message? Or was the page unresponsive? Have you tried adding contacts through a different browser or a private/incognito window?
Knowing these details can help us to troubleshoot further. Feel free to respond to this post. If you wanted to continue this conversation privately you can also email us at social_support(at)constantcontact(dot)com with your username and a reference to this post.
