Cancel hulu

I was sent an email notifying me that Hulu premium would be renewing, but I don't want that. I no longer have television service, but I think it was started through my set top box when I had one.

The chat assistant failed to work, and calling 1800xfinity led me back to the chat assistant. I read in the Xfinity forums that this is the only way to fix the problem. Please help me cancel Hulu.
