They call at 7:30 AM (Eastern time), consistently. They'll call two or three mornings in a row, then nothing for a month and start over again. It's a fax machine, probing for another fax machine. I have NO connection to these people, have never heard of them, no ongoing business relationship. It's put unsolicited junk calling.
NETPROWA. It's a fax for insurance and they include a local number to fax back and a "removal" number of 888-261-0323. If you have a few minutes, dial the number and leave a random 10 digit string for removal...about 20 times--each with its own call. Let's have fun with them. They have to pay for every toll free call.
I just filed a complaint with the FTC for this company, I'm beyond furious they called me at 6am waking up the whole house only to hear a fax beeping on the other end.
