If you really want answers fly to Charlotte and in a very civil and diplomatic fashion you knock on the doors of Eyetalk and Ross Hefler, Ronald Carter, i think he has an exwife, Ronald Carters parents and if nobody answers leave notes on the door and while your in the neighborhood leave a message with the neighbors, and if you really want to be effective arrive on a Friday and stay thru Sunday. Do the same process all three days, and if you dont have any answers by Sunday build a picket sign and carry it on PUBLIC PROPERTY in front Carters house and Ross Heflers house that says REVO WONT PAY and EYETALK wont Talk and with your other hand use your cell and call the local media outlets and tell them somebody is carrying a picket sign they always show for that crap. Carter is known in the area I think he had a nice position with the city. On Sunday morning you could always follow Carter to church that's always a great place to get straight answers.
And if you got real guts carry it in front of Carters parents house.
