Same thing happened to me. Robo Ashley calling to inform me that I won a million dollars for registering on line. Said I never registered for anything and then got disconnected. Was not a real person calling despite "trying" to sound like one.
ashley called said from a company I didn't catch name and asked if I could hear her. When I responded yes, the line went dead. Blocked caller. worried that the call was trying to get working phone numbers.
