No. While we don't have a phone number for support, you can still easily contact us for support via our Contact Us page on our main site or by opening a support ticket within the Support section of your site manager.
The best way to help us is to provide as much information as possible. In addition, if you can reproduce the problem repeatedly -- that will help us out immensely as well. Just write down the detailed steps that reproduce the bug and send them to us by opening up a support ticket found under the Support menu of your site manager. Include URLs to the problem on your site where applicable!
New features are usually announced with new releases of Squarespace which are listed under the Service Updates found on the Overview page of your site manager. Naturally, not all features suggested are actually implemented, but we do read and take into account all feature requests.
