I'm not sure about DoD, but clearances through OPM slowed to a snail's pace after the much-publicized hack into their records. While it's likely not what you want to hear, about the only thing you can do is worry and wait. 10 months *seems* like a really long time, but I've known clearance processes to take several years. As far as I know, there isn't anyone you can call to speed up the process. There's a well-known saying that I've heard at various places, and that's that everything "moves at the speed of government." Chin up, and before long you will hear something. People will start calling you to tell you that government agents had been around to ask questions about you.
