banned for no reason

Good morning
I was playing on my new human rogue Shokaze that was lvl 6. I went to stormwind and was disconnected for no reason , and then , couldn't log-in do to a permanent ban.
I think there is a mistake cause i did nothing against the server's rules.
I remember asking on the chat for a good spe for rogues that wanted to pvp.
Please review this case and give me an explanation.
Thank you for your consideration.
