My daughter just received a call from this number and he asked for me. When she told him that I wasn't available he said I'll call back and hung up. I tried to call the number back several times but it just rings busy.
I just received a call from 317-671-7455. When I said Hello he cheerfully asked if "is this the head of the household?" I said "I'm at work and who is this?" He said "no problem we'll just call back later." I blocked the number!
