I can see that there's been several posts about this previously, and now its my turn. I cancelled my Xfinity service about a year ago, and returned my modem. I just received an email from Complete Recovery Solutiosns about a cable box, but I've never had Xfinity cable. It feels scammy, but from other posts here it does seem it may be a legit company. How do I resolve this?
