Get a call blocker, the scammers will never stop using their autodialers.

Go to the last page, as this thread began in 2012.
This number has been calling sometimes twice a day. I have requested FOUR times to be removed from their calling list to
no avail. Even dialled the number and left a message on the answering machine, apparently useless as they called again
twice the following day. This is starting to become harassment and I shall send the number to the Attorney General of NYS.
Surely something can be done or being listed on the Do Not Call Registry is useless.
