Posting this here, especially posting only what you did, will not get you anywhere. We are just players, or Arbiters but they cant alter anything more than we can. You should have received a reform card, try logging in. If not there, check your Email and spam folder. If its not anywhere, make a support ticket and I am sure they will be glad to find it for you.
There is no chance that you said just "GG EZ" and got permanently banned, there's something else going on here that you are not telling us. Hiding information will not help you in any way size shape or form, and just what you are telling us sounds false and incredibly incomplete. Also, as for what crime you have committed? I wouldn't go as far as to call it a "crime" but I take it that you where banned for toxicity, and you would have gotten multiple punishments in the past. Flaming players and ruining their experience is pretty much a "crime" according to the rules of the ToS. If it was a permanent ban for toxicity, then you didn't treat other players like human beings.
edit I checked your past posts, you where incredibly toxic sounding, complaining about being placed with "noobs" and blaming them for your flaming. Again, you didn't treat them like humans. Your account is not going to be unbanned, you where very clearly highly toxic. If you make a new account, best of luck, and keep this in mind before you type that toxic sentence and hit the enter key.
Seriously, after looking at your other post, the fact that you included that "I have feelings too" and "I am human too" makes your position far worse. You flamed people, insulted them, probably hurt their feelings very badly, and made them feel like crap, and then you have the nerve to complain that you have feelings too after that? I am sorry but saying that will earn you exactly no sympathy whatsoever, because of how ironic and hypocritical it is.
I'm writing this with tears in my eyes ,I have feelings too, I want my account back.I don't know why I got banned?
I just said GG EZ every game i win,got banned but no reform card?
what crime have I committed?i am also a human being too.
