I keep getting calls from 713-568-6986. Calls are incoming back to back. All times of the day. At one time I turn off my cell phone which I guess the block the number so it says unavailable, but when they call my land line shows the number, so I blocked it to go into voice mail, but no message.
This number called me this afternoon. The voice mail said that it was a State Prison in Coalinga, CA... it was just saying if I wanted to accept the call press a certain number or if I didn't want to accept it to hang up. Weird.
