I Keep Getting Texts Asking Me To Return Equipment - I Used My Own Equipment, There's Nothng To Return

Hello. I’ve been receiving texts about returning my xfinity equipment after I canceled my service last month. I used my own modem, router and Tivo box! When I click on the link in the text, nothing is listed to return, which supports the fact that I have no equipment to return. I just want to make sure that I won’t be fined.  Please help, thanks!
