Filing a FCC Complaint

I’ve been fighting with Xfinity since March 12, 2024. My monthly bill was up to $207.65 for tv and internet (barely any channels and most were all re-runs). I changed to a cheaper plan and signed the 1 year agreement. Moments later I received an email that they were not going to honor the agreement we just signed. I was not offered any other deals at the time. Multiple agreements were signed and changed in March. Fast forward… I now have an absolute garbage plan (Now Tv with internet and Xfinity streaming app). I was assured that using the streaming app while at home on my WiFi I wouldn’t use any of the data included in my plan. With that, I figured my data plan would be enough. As I get a few days and weeks into this new plan I realize I’m using quite a bit of data though I’m only using the xfinity streaming app through Xumo box. I took all of my cell phones and computers offline to see if they were the cause of so much data. I checked the internet usage before I “unplugged” all other devices. They weren’t the problem. It shows I used 81G in 2 days while ONLY using the app. I contacted customer service today who assured me it doesn’t count. I was transferred to another department to have credits applied to my account. However, that didn’t happen. I was told they would not be issuing any credits and the app does in fact use data.

(the data plan I’m referring to is what is included with my internet plan, not mobile plan)
