Getting calls on my brand-new un-published ATT cell phone and no messages from this number. 11/27 and 11/29 in 2012. Not sure how I ended up on their list. Also a 412-346-4850 number on 11/28 inbetween this phone number's calls. After reading all the other comments on this site, I would ignore or block them.
This number called me 6 times in a row. If you are not in my phonebook my phone does not ring and i never set up the VM. So they can call 100 times, i don't care.
