Who called from 3022120615

Rang once just a minute ago.

Rang once and disconnected a couple minutes ago, no message and so far no call back.

Range twice and hung up.  No message and I do not know this number

Called my cell and hung up after one ring. This sounds like the scam that was reported on the news a couple months ago. People were reporting this same thing, but if they tried calling it back, nobody would answer, however they were getting $20 charge on their cell bill for calling it. Needless to say,  I will NOT be calling it back.

Same as the others, called and rang one time.  They hung up and did not leave a message.  I am registered on the "Do Not Call List".  Tried to call back and  it is a busy signal.
