700 dollars for data????

Good afternoon @user_2h3yhc, and thank you for reaching out on our Community Forums with your data concerns on your mother's account, we appreciate your time and allowing us the opportunity to try to turn your experience around. We're sorry to hear about the frustrations trying to get this resolved and assure you this is never how we want our valuable customers to feel. We'd be happy to look into the data charges further and if needed, get a ticket submitted to help resolve this as soon as possible.

May I confirm if the data overage charges were related to her XFINITY residential or mobile account? Additionally, please make sure that you are listed on the account so that we can discuss her account issues with you further. For privacy and security purposes, we do require that you be listed as an authorized user. If you're not listed as the account manager already, you can get added by following the instructions here https://www.xfinity.com/support/articles/primary-and-secondary-accounts. 

If you are already on the account or once you've gotten added, please send us a Direct Message with your name, the account holder's name and the service address including any applicable unit or apartment numbers. To send a "Direct Message" ("Private") message:
