I have been with XFINITY for 13 years and seven months

I’m just leaving a feedback. I have been with XFINITY for 13 years and about seven months and I returned my security camera and they still trying to charge me in October bill and November bill even though I returned my equipment. I don’t think it’s fair and I’m writing this to leave a comment and I’m gonna leave a comment in Facebook and every social media to let them know that XFINITY is trying to steal from their Customer, i’m going to report them.
