Name on phone for 310 855 9521 is TTI.  They also use 7560, 9307, 9247, and 9521. The 310 855 7560 number is the Voodoo Room, 8948 Santa Monica Blvd, West Hollywood, CA 90062.  When I answer they always hang up.  No idea what they want.

I have talked to one of the bozos twice .... and if you tell them that you are not interested, or to take your number off the calling list ... they hang up on you.  They are the Trade Tech Institute and are selling an automated trading system (bet you, that it is a real winner!).   They have called me from at least 15 different numbers, and the first time I talked with them they refused to identify the company name and what they were selling.  They have been calling my number since October of last year ... and are seemingly the lowest of the low.
