MY IPHONE 4 IS STOLEN AND I USED ICLOUD IT DIDN't SHOW MY PHONE?

IT SHOWED MY CUZING PHONE So 2 PHONES ARE USING SAME ICLOUD HOW CAN I FIND MY PHONE Please Help

Added (1). Same icloud with his account and my phone has the android lock

1.did you set them up to the same icloud or were you using his account and did not sign in to yours?
#2 it's temporary in a place that can't reach the signal
#3 the thief plugged it in and programmed a new icloud.

I regret to say there's lots of stories about stupid apple service and the phone companies hooking up new service with no care that the phone is stolen.
