This number started calling me; 3 times yesterday and twice today. I suspect that it could be AT&Tas that would explain how they can call and not answer from the same number.
Same thing as the rest of you. No audio on the call and when I tried to call the number back, it was, surprise surprise Sargent Carter, not a good number. Have been getting this kind of stuff lately. Also, got one from 202-255-5871 saying they were a collection agency looking for someone named Celina.
