Streaming Cancellation

I just want to cancel my TV subscription portion of my plan online, I don't even have a box i just want to remove the cable piece completley. Xfinity assitant agent was incredibly helpful and nice but said i need to call or go in person to cancel, which makes me feel like there will be a lot of trying to get me to keep it.

I also keep getting texts about unused equipment i need to return that I have no idea about because I don't have it. 

Can I direct message and just have it done without sitting on the chat for 2 hours again or on the phone, it should not be this hard Xfinity.
