Cancel my Service I Want a Refund

I am posting here because the TERRIBLE customer service for xfinity won't connect me with an agent any other way. The online assistant is useless, the 800-xfinity number can't connect me to a real person, there's no email address, nothing.

I received the worst service today and my account isn't even STARTED yet. They couldn't even get it right trying to make my new account and get me set up. I want a refund on my initial payment. I will never use this company again.
