They are a very rude financial firm trying to get new clients. They repeatedly call my boss (who doesn't use voicemail) and want him to call them back. When I ask what it is regarding, they say it's private. When I tell them he likely won't call back without a topic - they hang up.
I returned the call. It is a cold call from a broker in NY - National Securities. It appears that he garbled the word "securities" in the message left for me, expecting that no one would return the call if they knew what he wanted. The work "securities" is a dead give away.
Thanks all. Now I know not to return the call. The voicemail i got today (9/19) was the same as listed above, and i was pretty sure it was a cold call.
