Is my phone provider.I get a call. "We're upgrading the 4g network in your area and you might lose service for a while. Verizon will comp you, write down this authorization number. Also, please verify your name, last four, billing address..." Name? Ok. Addy? Fine. Last four? FOR REAL?At which point I have to stop the guy and ask him why all that is needed. I mean, you called me. Can't Verizon tell from their end how much time my phone is off the grid and just comp me? Jeez. Want my bank account number too? Not sure if it's a scam or not...but I bet there is a better way to inform people. Besides...what if I give the wrong last four? You're right....someone stole my phone in order to steal this activation code. Whatever.
