How long does a county in TN have to report to the Gov over a case?

My husband was charged with FUCC (fraud use of credit/debit card) in 2012. At the time of his arrest and going before the judge, it was a class e felony. The judge told my husband that if he paid his restitution, fines, court costs and probation, it would be dropped to a misdemeanor. He done everything he was suppose to. Last Feb, he tried to purchase a firearm, but when the background check was done, he was denied because it came back as unknown. He filed an appeal and was given a "conditional proceeds." The county he was convicted in did not send the documents into the state within the 15 day period. So, my husband called (by accident) the FBI instead of the ATF. They told him that counties take their time doing this. How can we get the county to send in the paperwork? How can we find out if his charge was dropped from a felony? And what can we do about this because this has cost him more than just his ability to purchase a firearm.
