Hello, tpickering2. Welcome to the Xfinity Forums!
Its very important to us that customers are able to freely review and manage their accounts. I would be more than happy to look over your account and get it fixed so you can access it, as well as investigate that $20 increase. Please send me a private message with your first and last name, as well as your service address so I can assist.
