I've received 2 calls from this number 424-235-5974 today. The first time they called was 5:26 PM, 11/19/2015. I answered the call, but it was just dead air. I said hello several times, and eventually the line went dead. They called again at 7:10 Pm tonight, the same date. I did not pick up. They let it ring about 4 times? Did not leave a message. It said FIFTH THIRD on our caller ID for both calls.
