xfinity NOW internet issues - Need help from experts, xfinity assistant is no help.

I activated my Xfinity NOW Internet service today and paid $30 for 30 days of service. A few hours later, my internet stopped working. When I logged into the Xfinity NOW app to restart my modem, the app said I had no service, and I received an email stating that my service had been disconnected.

The Xfinity NOW Assistant couldn’t explain why this happened and asked me to pay another $30 to reactivate my service. I’d like to speak with a specialist who can investigate why my service was disconnected and help ensure this doesn’t happen again.

Thank you.
