I got a call from this number too. The only possibility of this number leak for me is that I tried to clal a number of craigslist.org for a toyota corolla sale (650 771 1171) and I recieved a message that the voice mailbox has not been setup. Did anyone else call that number?
I picked up and a woman voice (machine) said "Good bye".. Then hung up. Stupid.
I called back several time (to scream at them haha). But no one picked up.
Didn't pick up the call. They did leave a 47 seconds voice mail. All I got was "Hello are you still there?" twice with 15 seconds pause in between. Male voice sounds like pre-recorded message. Did not know scam has automatic system nowadays.
