Delete character

I accidentally deleted a character, is there any way to get him back?

Website > Services > Char restoration.

You do not have enough coins to purchase character restoration. What is it? I am offline in the game.

Where can I get points or coins?

There's free option if you click "Coins" -box. The free option is once per 7 days per account (not character). Use it wisely.

EDIT:
Points - WoTLK Point Shop and Activity Rank
Coins - https://www.warmane.com/account/donate and if premium account, selling in-game stuff via https://www.warmane.com/account/trade
