Unknown caller.

Phone number keeps calling me with no voicemail or message.

added to spam list......keep calling everyday..

Keep getting calls from this number... when I answer there is no one on the other end.

I didn't answer.  They let it go to voicemail (I presume because they're on the type of telemarket system that alerts the telemarketer caller when the consumer answers the phone).  They left no message but 5 seconds of background noise could be heard.

Keep getting calls from this number with no message left. I signed up for Comcast last month, so assuming this must be from them based on other notes.

Just got the call - no message  -- any ideas?

This person said they were a third party vendor from Comcast.  They didn't (refused) to give name.  When I asked how they came to get my cell number (which has do not call registry) they wouldn't answer me.

They call almost every night around 7pm. Don't leave a message. I am on the Do Not Call List.

I just got Comcast Internet and TV, and now I get a call from this number everyday, but no one's there when I answer the phone.

Called again, no voice.

Irritating call from Comcast, supposedly they call you if you have Internet services and they want to ask you questions (most likely for marketing purposes). Rude, disrespectful, hung up the phone as I was asking for my number to be taken off their calling list.

Same.. again, no message

Call with no message left

Couldn't hear anything from otherside ... and then very slow speaker, I had to hangup.

Nobody spoke on the other side for 5 seconds then they hung up.

This is Comcast

call with no message left.
