I Cody I Was Banned By No Reason:/

Hello, I was I Cody I untill it got banned...
I see i got banned because the guy i sold an account to said I recovered it.
But I haven't.. Idk how I can proof I didn't but the recovs was old and my pc have crashed so all files went away [ this include old pass,recovs and other stuff about the account he say I "recovered".
If there is any way I can proof I didn't recover [ I couldn't recover tough ] I would like to show it to the mods.
Please!
Give me back my sythe account that i worked so hard on
I didn't recover it..He must either been hacked/keylogged... Or he is lieing.

Please Let Me Stay In Sythe.
