This scammer calls numbers on the national do not call list in violation of the Telephone Consumer Protection Act. While they do have an operator on the line shortly after the call is answered, they act like the call has been dropped if you ask for a company name, address, or phone number rather than provide this information that any legitimate company would gladly provide - and that they are required to provide by the TCPA. They ask for the person responsible for the web site, and want to talk about what marketing services are being used to promote the site, but since they hangup rather than provide basic information about themselves, you can be assured it is a scam. Do not provide this scammer any information.

From San Pedro, CA - Another new harassing number called and left no message on my answering machine.
I no longer block individual numbers as these scammers use too many different numbers when they call. I use a call blocker that blocks the entire area code.

Called twice, and left no message

Got a call too and no message.  The call was to my google number that is posted on a website for my business.

Called me today left NO message. Heard a call center in the background
