Number not recognized, I didn't answer ... no message was left.

unfamiliar number

Called but left no message.  Decided to call back as I did not find any negative info.  Said it was Comcast but hung up as I have heard about Comcast scams.  Cannot confirm it is a scam as I am a Comcast customer.

I believe this is a scam that records your voice. This number called me and then called another number three way which was recorded to my voicemail since I didn't answer. I do not subscribe to any cable service, so if they say they are Comcast, it's a scam!

Just picked up this call.  They told me they were from Spectrum; I wasn't getting the newest services, so they wanted to transfer me to a sales department. "  I hung up.
