Same here. I have talked to them an yelled at them and told them I would come see them and bother them at work. The more I complain the more they call. Several times a day for weeks now.
They just called again! That's twice within a couple of hours. This time I took the call.
It's some online yellow pages outfit using offshore telemarketers. They said they wanted to update my business listing. I interrupted and said they'd reached a RESIDENCE, and the guy apologized and said he'd make a note of it. Hopefully they won't be calling back.
I know how they got my number, though. Several years ago I registered a domain name for my friend's business and created a webpage for her. I did so without the new privacy options offered by outfits like GoDaddy now where marketers can't get contact information for you. My contact info is now out there as a business from that. :(
