How do I downgrade from TV+data to a data-only plan?

The account management interface won't let me do this.

I've seen other posts in this forum instructing people to "direct message", which I don't appear to have access to.

I've also tried getting support through live chat, but nobody was available.

HOW can I get help in removing the TV part of my plan? I would just like to have a data only plan?

Thanks!
