All ready enrolled in home internet plan but not able to access mobile app to finish set up

I am extremely disappointed and frustrated with Xfinity’s service. I signed up for a home internet plan this week, yet when I try to set up my internet, the Xfinity app repeatedly tells me that I am not an Xfinity user and that I am not authorized to access the app.

I have already confirmed in-store that my purchase, plan, and account information are correctly entered in your system. There is no reason I should be locked out of the app.

This has been a completely inefficient and confusing experience. I expect this issue to be resolved immediately and a clear explanation provided as to why this happened in the first place.
