I just received a call from this number, and in the recorded message they asked me to return the call at (866) 771 5596. I looked up the 866 number and people have made several complaints about it, but none for this 415 (San Francisco area code) number.

I keep getting a call from this number but no messages left who is this caller

A person with a very heavy Asian-type accent who called herself Eva called trying to get information on one of our employees. When I tried to call her back, the line buzzed very loudly. Tried again and a recorded message said that this number couldn't be reached "as entered."

I just got a call from this number, but when I call back it's a busy signal. And no one left a message when they called.
Does anyone know what this company is?

The number 415-376-1385 belongs to California Bureau Services a third party collection agency for hospital bills/credit cards.
