Ok heres the deal, i am not your life saver, but you cant really get unbanned.
You would need to hack the VAC servers to get in, and unban.
But thats way to dangerous. My advice, get a new account. If you have the Box from CSS. Just reuse the CD key, that way you dont need to rebuy the game. Now if you dont own a box. then my friend, you'll need to rebuy the game.
Sorry, you should've never given out your password.
Some of can hack, but i dont think we are stupid enough to hack into vac, unless we can back ourselves up. I could do it for you, but i need better equipment, and a better computer, i am just not set up for hacking into Anti-Cheats. I need to rebuy a few things.
Kinda poor, so i wont be hacking Vac for another month or two.
I could try and hack Punkbuster, and unban everyone like a few hacker friends did. but not now, now i need to focus on some pubs, and School.
