My family received a call from the phone number (480) 812-3745. Turns out it belongs to a scammer who wants your credit card info. I don't want anyone here getting duped. we verified through our card company that nobody affiliated with them called us. A quick Google search turned up other complaints from various people. He will ask about your visa card, and if you tell him you don't have one he says they handle Discover or insert common card name here.
So hang up if 480-812-3745 appears on your caller id.
