Annoying texts about UNUSED equipment

I keep getting texts that say

Hi, Xfinity here. Reminder: Return your UNUSED Xfinity equipment today to reduce your monthly bill & protect the environment.

As far as I know the only unused equipment I have is the useless streaming box I was forced to accept a few years ago, and I'm not paying anything for that. I own my own Cablemodem and router and have no TV box. Do they do this to everyone, or am I just that special?
