Fill this out. Be sure to follow the directions perfectly.

Also:

Don't pm staff members asking for an unban. It's gonna hurt your chances. I just happened to see the profile page tab filled with you asking for some assistance. Best to avoid that in the future.

Use the report, and wait it out. I'm assuming it might get addressed a bit faster since it's a weekend, but don't quote me on it.
