this # calls and as soon as i say hello they hang up

I get at least 4 calls a day. Mostly at night.

I keep getting calls from this number but I don't answer because I don't know who it is, they never leave messages...does anyone know who it is?

i get several calls a day- and late evening.  most times they hang up.  three times they said they were following up on our online inquiry about making money on-line with google and had way too much information about us.  i asked for a telephone number.  "Leah" said i could get it from caller ID.  i told her it didnt work, she gave me 877-340-4694.  i just tried to call (8pm PST; Oregon) and the voice message informed me the office was closed.  i guess i will call again tomorrow.

This number, 213-239-2892, called me at 9:52pm last night.  They have repeated to call me 2-5 times a day the last 2 weeks.  Looking this up online, it's a telemarketing call, and well beyond the legal dialing times.  I will sue whatever company it is if I can find the information.
