I have had a similar experience. For the last two days I have been getting calls from this number. No one says anything when I answer. When I call back it is a busy signal.
They have been calling for 2 days now. They don't leave messages. They don't answer when I pick up the call and I only receive a busy signal whan I call the number back. All I know is that it's an AZ area code.
I got a call today from this number. They gave no company name, or any personal name, just asked for me by my legal name, which I obviously don't give out to just anyone. I wasn't there to receive the call, my boyfriend was. When asked to take a message, the man on the other end said goodbye very quickly then hung up. When I looked up the number, it said the most likely place where it was registered was Cornville, AZ, which is near Sedona, AZ and is a landline.
