I dont answer calls from unknown numbers. If they leave a message, they're likely more legit than if they don't. If no voicemail is left, ignored and blocked.
Caller ID says "Gallup Org". Maybe it is, maybe it's not. Either way, when they start paying me for my opinions, I'll start answering their calls. Until then, BLOCKED.
don't recognize number. says GALLOP ORG on my id. I don't do organizations that call me. If I do organizations, I call them & if they need to call me back, I will know what number they will be calling from, not some scammer or crook trying to steal from people.
