They called and left a brief message. When I called back, they got my attention by offering a $100 gift card for Walmart. I said ok, and proceeded to let them send it to me. However, the catch was I needed to pay $4.95 to "unlock it". I said no. I said if someone wants to send me a gift card, it should be free. That's the idea of a gift card. I hung up.

Hung up after two rings. No idea who was calling.

two rings then hung up

Two rings and then hung up.

Called my cell phone and hung up after one ring
