Returning xfinity equipment

Hello. I’ve been receiving texts about returning my xfinity equipment after I canceled my Xfinity service last month and started the Xfinity now. The only thing is my own equipment! Furthermore, when I click on the link in the text, it takes me to a page to start the return process, but nothing is listed, which supports the fact that I have no equipment to return. Has anyone else been in this situation? I just want to make sure that I won’t be fined or something due to this obvious error.  Please help, thanks!
