This is a new one. Still a loser, or else someone dialing a wrong number.

keep getting calls they don't leave a message & when you call back it just rings or hangs up?  

They r even calling on my new cell phone. I do not answer.
Oh and by answering, if you do, now they know the right #. Turn
them in to the FTC. as well as, put your name and phone # on the DO Not Call list..

called me too (Microsoft they say) wanted access to my CPU. Microsoft does not call people. I've had these calls before and I love messing with them until they figure out what I'm doing and hang up.

Called, left no message, blocked.
