They have to provide identification information per the Telephone Consumer Protection Act of 1991. File an FCC complaint against them. They could have forged the caller ID with a residential #.
If one chooses, one may observe a similar web site for "617-591-6225". In said web site, it is recommended that one call the aforesaid number, listen to the pre-recorded "prompts", and allow them to REMOVE one from their obnoxious missives. I trust that this will solve one's problems and allow one to continue one's program of gracious living. Thank-you kindly.
This number calls repeatedly. I finally started answering and they just hang up. It is terribly annoying and I can't figure out how to stop them. When I can back they don't answer.
