I called this number back and a lady answered saying just "hello" and not very friendly. Then when I said missed a call from the number, she changed her tone and claimed she was calling on behalf of Comcast! I told her it was weird the she didn't answer saying something like "thank you for calling comcast" instead of just "hello". She has nothing to say about that! Definitely a scammer! Beware!

Just got my first call from the number, no idea who it is...

This number has called my cell no less than 8 times in the last few days.
