Who called from 9012030294

Phone rang once and hang up. No voice mail. Checked the comments here and did not bother to call them back. Thanks for creating this site.

Call rang 2x and then hung up.

Same thing happened to me, hung up right as I picked up.

Phone rang barely long enough for me to see it was an unknown caller.  Left no voicemail.

Number is now BLOCKED.

Rings once or twice to trigger your cell phone history of missed calls.  Call it back and It's a telemarketing recording for "Rewards Redemption" offering a $100 gift card if you press "1".  I don't think there is any value in that.  It's probably best to ignore it or block it.
