This number keeps calling daily, and asks for the owner by name. The same guy every day, and he won't leave a message. He just says he'll try back. Caller ID says National Secrts, same as others.
Calls several times a week and asks for the CEO by name, when asked what he is calling in reference to he states 'vertical integration', pretty sure that isn't a thing. I put him on hold, told him the CEO wasn't available and I'd be happy to take a message, he says he'll call back. Scam. My advice, have some fun with it!
