This number calls my cell phone 5-7 times a day. 2-3 calls at a time about a minute apart. When I answer no one answers back, but i can hear a person speaking a foreign language in the background and then a dialing sound. As if they don't realize I answer and they are trying to call back. When I call the number an answering maching comes on and reads back the number then says they are not available please leave message.
