Someone faked an account and sold it

 
 
 
 
 
Good day,

Unfortunately, I can't find any other support and would like to turn to this because I can't find anything else except "report bug". If there is a report for that, how in my case could you send me a link to it?

I had a bit of an argument with another Minecraft player, he later faked an "account sale" and wanted to send it to you, of course I wanted to get ahead of him because something is wrong and I don't want to be banned for no reason Here is a picture that this player has faked a sale to get Mojang banned.
