Over change. No landline

Hello chuck.o. Thanks for reaching out to us on our Xfinity Forums for help with the charge for Xfinity voice unlimited. I'm sorry to read that you may be being billed for a service you did not know you have or are not using. It's possible that it was part of a bundle package that may have been selected for the account at one point. I found my mom still have a landline on her account recently, and she hasn't used that number is several years. 

I know that added cost is anyway can make thing unaffordable, so I would love to help out and look into this for us. 

Can you please send us a direct message with your name and service address? We will dig into this and figure out what's happening.
