YoutubeTV. I cancelled FiOS TV two weeks ago and use YoutubeTV to watch Celtics and everything else.

Interesting. I did my change online via the website, not over the phone. Have you tried doing it online or in their app instead of via phone?

I dont think this is true, as I just dropped both cable and phone from my plan and only kept internet.

Are you under a contract with them? Maybe that is the case if you are under contract, because I wasn't under a contract, just month-to-month
