Got a call from my cell phone at 9:23 am on 3/23/13. I don't pick up unknown number knowing it's a scam. Didn't leave any message. I got calls from this number before.
Follow-up: report this and all other phone scams to the FTC. If your number is on one scam list, it will find its way to many more. FTC can log, track, and detect patterns.
