I do not believe the case will be sealed under the facts that you give. If it is listed as a felony by mistake you need to follow up on it. Prosecutors are very busy and spend their time on existing cases. Since your file is closed it will probably be something that is low on the priority list. Too ensure that it is straightened out you probably need to consult the attorney who represented you to begin with. The attorney will have as much interest as you in getting it straightened out.
