said by marksss : What are your thoughts?
You made a smart move, asking around/checking it out, before jumping at a suspious, unsolicited over the phone offer.
Even though many here have said it MAY be a legit offer, the penalty for being wrong and giving your account info to a scammer MAY be very high.
So if you have any misgivings, just hang up and report it to comcast security (who can probably find out if it's a real offer, an overzealous sales rep, or an outright scam (the "today only" would have me running away)
