You could say that.

you've got to tell them your email you have in the account, or your username exactly, or your udid,

They can check logs and see what's going on. Don't bother the lower staff about it because they probably don't have access to that stuff and will just refer you to the higher up.

Just try to memorize everything you did, and don't leave any details out.

Don't worry, if you really didn't do anything they will unban you.
