calls 3-4 times day,hang up when answered. No Voicemail  when return call

This is "Yellow Pages".

Not the legit Yellow Pages listing that you receive free with a business telephone number. They scam you into thinking it is, but then you recieve a bill. You have trouble disputing the bill because they recorded you "updating' your company information - because you think it is actually Yellow Pages - then they use that recording to justify that you agree to the ad.

My advice... don't even talk. Then they cannot use even your simple reply out of context.

Just hang up.

We get several a day... sometimes just a hang up, other times someone actually comes on when you answer.

very annoying, calls the business multiple times no one on the line

CALLS SEVERAL TIMES A DAY NO MESSAGE NO ONE ON THE OTHER SIDE WHEN ANSWERED

I just added that number to my caller block list.  Every one lived happily ever after . . . for now . . . :\
