Who called from 4340372287

male caller knew my name but refused to identify himself and hung up so I subsequently  blocked the number. (like it will do any good)

No message.  Caller ID identified as "Invalid Number".

This is the 4th unavailable caller I've had this morning... I'm so sick of these calls... I don't answer but it is annoying..Isn't there anything that can be done about it?

Received on my cell a full screen of data to accept. Print too small to read and disappears before I can find a magnifying glass.
