Who called from 6173605718

Called at 7:40AM Mar 22,2015,... also 10:48AM Mar 21, 2015,, on my  (PRIVATE) cell phone that the only person who would call would be my wife. All others do not know me. This is for my wife to call me ONLY. When I get a call on this phone ,it means there is a very EMERGENCY
I could seriously kill the owner of this type of call.  I would love to find him.

Rang twice and hung up.  No message.

Rang twice and then stopped. It is group calling and when some sucker answers the others go dead.

2 rings and hang up

I received a call from this number this morning while I was sleeping. No message.
