50% off promo ending

I received a call from [Edited: "Invalid Phone Number"] a voice recording letting me know my promotional services for 50% were ending at end of day today, and to avoid losing my discount I needed to call the phone number on my caller ID. Please beware these scammers are out this season and it will only get worse the closer to tax return season. I would hope xfinity comcast would address these issues ASAP. Thank you, happy holidays.
