Xfinity fraudulently charged me !!!!!

I moved in April 2025. I specifically canceled the internet service at that property, and established new service a year ago….I even did a chat months ago to confirm that I was not being charged for internet at that address. I had to put a new phone on my plan, and went in to the Xfinity store today. There were THREE separate accounts open in my name, and I found out I have  FULL YEAR’S worth of unauthorized charges!!!! Over $1,400 from Xfinity that was NOT authorized and should have been canceled…and the store could not get me my money back 😡 Why I earth would I stay with this company?! This  is criminal!
