This number keeps calling but never leaves a message.

Called today and didn't leave a message.

I get calls from this number every work day, but a different times of day.  I never answer and there is never a message left. If this was a legitimate call a message would be left.  I think I'll check to ensure my number is in the do not call registry.

This number has also called me for the past few days, around the same time. Someone probably sold out our numbers. Could be telemarketers or scammers....I would just ignore.!...Important callers would leave a message like civilized people.

They call me daily but never leave a message. If they want me to call back they'll need to leave a message.

This number has called me daily for the past 4 or 5 days. I don't answer phone calls from numbers I don't know, especially numbers from area codes I don't know. They never leave a message. If they want something they should at least leave a message.

They didn't leave a message

They say they are Comcast but ask questions about what services you already get. If they are from Comcast, shouldn't they know what I have signed up for already?  Bad Marketing!

Just got the call, didn't answer since I don't know the number and live far for the area code

Call from this number, left no message.

it is comcast

Just got a call. Put it on mute and let it sit. They Hung up after a minute of silence. Hopefully they will assume its a non working number since I answered before the person was connected.

I returned the call I received (they didn't leave a message), and it was Comcast.

Didnt speak anything after lifting the call.

Yea got a call from this number too...twice....I don't even live near there...didn't pick up.
