Xfinity keeps billing my account after cancellation, deeply frustrated and this is illegal

I wouldn't bother with a chat or even speaking to someone in a foreign country about anything related to Xfinity. They do not care.  We have been overcharged monthly even with a request to fix the issue and nothing is ever done. We turned our equipment in and waited to hear back on a refund owed us and they canceled out the request with no comments on why it was canceled. This was done in an Xfinity Store, they were super helpful. Tomorrow I will go into the store to cancel. It's been a waste of time and what they do for billing without showing charges, not taking off wrong charges and zero customer service> this all equals money to them and nothing more. We are done after 14+ years

Oh and I am going to report their unethical practices with billing and lack of response to our State Attorney's General's Office and the State Dept of Consumer Affairs
