I have tried calling this number back, but I get the message that the service I am attempting to use is restricted or unavailable.  When you answer, there is no one there.  These calls are constant and several times a day !!!!!!!!     The number is 415-121-6432       All I can find out on this number is that it is California ; San Francisco area.

Unsolocited calling

Please some one do something about this annoying phone calls.
Don't know what they're up to, must be something illegal.

I recieved a call from this number today with a female on the line saying that i particapted in an online survey and because i did that she was willing to walk me through a web site to recieve FREE gift cards and it is nothing but a scam

It is a scam. They want to walk you through a website for gift cards but you gotta give your credit card number to purchase other items. Do not do it. You will receive nothing but more calls and lose more money.
