This number has been calling repeatedly and often hanging up as we answer. We traced it to Graven Austin Drake, which is a telemarketing company. Call (800) 888-6780 and ask to be removed, they were very nice about it, so we'll see if it stops the calls. See their website here: http://www.gad-inc.com/index.php/contact-us
They called every day for 2 mos. If you pick up after 4 rings or so, there's no one on the line; finally I pick up and when I answer their questions about who we are (a technical magazine given to a family member "for free"). I was told that if they call on a yearly basis to update subscriptions. Then they called the next day, (passive-aggressive, I would say) stating they needed to ask me questions again because it didn't go through, maybe there was a "technical issue". I asked them to take it up with their IT, as they "record messages for quality".
The company and employees are NOT STUPID, They are given a FREE PASS TO HARASS the public in the name of whatever print magazine contracts GRAVEN AUSTIN AND DRAKE to validate the targeted subscribers for the advertisers.
