Who called from 6504894932

Caller called and hung up. Caller id name was San Carlos.

Called several times and never left a message.  When you call the number back it is silent and then gives you the busy signal every time.

Call and hangup one time called back no ring and busy tone

Also got a call 8:39pm from this number, no message.

Received a call at 1858 on the 12 of March of 2008. They claimed to be from the San Francisco Chronicle. They were unable to answer the question "Where did you get my phone number?" They said they called people randomly. And subsequently said they would remove me from the list. Idiots.
