Need help unbanning an account

I've had the misfortune of being banned for third-party programs and is now seeking some advice how to formulate a ticket.

I have had the account since vanilla, with basically everything completed in the game and would be more than sad to have it lost forever. If there is any anyone kind enough I will be forever grateful that could point out what a ticket should contain and what shouldn't, or if even better you would have a pre-written short-story.

I will gladly pay if it's required, please send a private message.
