Who called from 3072576213

I just got a call from this number, so I picked up the phone but didn't say anything. There was dead silence, so I hung up.

Received 4 calls today from the number in question. (2-25-14)
Since I don't know anyone in Wyoming I didn't bother to answer.

this number calls everyday - about 2 - 3 times. very annoying!!!!!

Called 2 days in a row...no message.   I called back and got a fast busy or "call cannot be completed". I know on one in KY.

I have don't recognize the number and I don't return calls to an unknown number!!!!!
