Who called from 4152828986

CALLED ME AT 3AM. THREE TIMES.

Caller wanted to speak to the man of the house - for a survey.  I'm concerned they wanted to know if I was alone or not.

I just received a call form that number, when I tried calling back I received a message saying that the number is disconnected...what's up with that?

I received a voice mail message from San Francisco General Hospital 415-282-8986 advising me that I had a scheduled appointment on September 12, 2011 and I never made the appointment.

Received numerous calls from this number, 415-282-8986, on my answering machine. No message was left, and the caller I.D. showed it was from San Francisco General.
Calls were made Sundays @ 515 p.m. and Fridays @ 10:30 p.m.
