Regarding xfinity free mobile line for 2 years for military members

Hi, I was supposed to receive two years of one free Xfinity Mobile line through the military benefit when I bundled it with my internet service.

However, it has now been exactly one year, and my bill increased yesterday. I noticed that the military benefit is no longer being applied to my bill.

I contacted an online chat agent, but they were unable to assist me further, and the store was not able to provide much help either.

Is there anything I can do to escalate this matter or have the 24-month military benefit reviewed and reapplied to my account? I would really appreciate any guidance. Thank you!
