Beware cowbulls may be a shill preparing this number to be used in a comcast scam or this may be a legit comcast number. Best thing to do is check with comcast yourself using a number from a trusted source like your contract or phone book but don't ever give personal info to a stranger who calls you, even though if they claim they are comcast.
Got a call from this number today and wanted to know if my service was working. Came up as Comcast Spotlight. I knew that my phone # was not associated with the account and then she tried to say she couldn't give me any info. Wanted to know my address........sounds like a scam to me!
