Worst Customer Service Ever - 20+ Year old customer - FRAUD and THEFT by Xfinity

I have never been treated so badly in my life by a company I often suggest to friends and family. AFTER 20+ Years being an Xfinity-ComCast customer of Cable TV, Internet, Security and home phone services at mulitple houses. I am spitting feathers. I only hope and pray they actually do record these conversations and teach customer service people what not to do. After talking to a nice gentleman about a billing issue where it turns out Xfinity has billed me for a cancelled service for nearly 2 years (Yes, i have multiple Xfinity accounts on multiple properties and didn't look close enough at my bank statement). I called 2 years ago and cancelled service, next day went into a store and returned my equipment and still was billed 2 years. VERY Easy for the Supervisor who was so disrepectful to see there was NO Equipment with my account and when it was turned in to ask me if i had record of calling in to cancel my service. [Edited: "Language"]. OF COURSE I called in and then turned in the equipment the next day. The nerve of this terrible customer service person from the call center abroad to ask if i had proof of my call to cancel.  SO for 24 months of illegally billed service, he said he could only credit me back 3 months. And I would need to wait a few weeks to collect. Then I asked how I am to be sure he cancels my account this time he has the nerve to say he cant text me a cancellation only email it. And that could take a couple days.  So Sad for a company I said was so good to so many people. Its experiences like this with these large companies who lie to the media on thier commericals about customers being important. We are not. We are simply a number as refunding me a portion of what is due will apparently break the earnings for the quarter and cost the company billions in stock market value Market Capitalization. XFINITY. DO BETTER. [Edited: "Inflammatory"]
