Same thing - rang for half a second and they hung up. No message. I thought it may have been a wrong number, but now that I'm getting scam calls every other day on my cell phone, I thought I'd look it up, and sure enough...I'm not the only one.
I got a call that rang once and hung up no message. Rewards Redemption when I called back saying I recently visited a website. Scam. I never give my real phone number for anything.
