Not sure who this is but always check here first. The phone didn't ring, it just popped up as a missed call. How do they do that? No voicemail. My phone has this area code, but I now live in the east coast, so it's nobody that knows me or they would know I moved.
Bait call. They wait for you to call back and robo voice informs you that you have "won" a $100 gift card. All they need is your name/ DOB/ address/SSN/ routing # to your bank account. Hmmmmmm... sounds "legit".
