@user_cf3xxf​ do you use their modem? If so tell them you want to swap it out. I did that as a Hail Mary and it worked!

Hello, user_cf3xxf! Thank you for reaching out about the data usage increasing vs. what you saw last year. Our Customer Security Assurance team are the experts with data usage and run tests on your service when you reach out to them to verify what is being reported. Have you spoken with that team specifically?

Have you taken any steps such as changing your WiFi password to ensure only your devices can connect?

Another thing that can help to test where the usage may be coming from is to only connect a devices or two, monitor the usage. Continue to add devices slowly and monitor the usage. 

Same issue for me, sudden increase in Data, exact same pattern!

@XfinityRay​ not sure which team worked on the issue. New modem solved it. I’m convinced it was a faulty modem.

I did contact you Customer Security Assurance team and they assured me that the issue must be on my end because I don't use an Xfinity router and then attempted to get me to sign up for your unlimited data plan.  I'm now contacting my router company to provide a report of the actual data usage to provide Xfinity.  You all are setting yourselves up for a lawsuit for trying to scam your customers into signing up for unlimited data
