Who called from 6412433198

no message left after they called; call cannot be completed at this time or call did not go through when i call back

Called main company line. The phone rang 3 times and they hung up. I guess they knew I wasn't going to answer because their caller id is: Directory Line.

Called our unlisted company back line and didn't leave a message. ID says Mason City, IA. Heard another website say it was yet another marketer I need to block.

robo schmuck wanted me to verify my business name.

Number comes up with 11 in front on my t-mobile iphone:  116412433198.   Says "IA, USA" - so we know its a scam!
