It doesn't look very good for your characters I am afraid. As far as I know Game Masters never restore deleted characters.
Also it sounds like you have been sharing your account and that's = permanent ban.

You may not purchase, sell, gift, share, lend or trade any account, or offer to purchase, sell, gift, share, lend or trade any account, and any such attempt will result in an immediate account closure.
My suggestion to you is to start a new account. Read the rules and be more careful in the future.
