WotLK They deleted my character by mistake

[xAlkinperpro11x]

4 months ago I was banned and recently unbanned.
I had a character called nimeguri rogue level 80 that when I entered the account was gone.
Please I need a help since I tried a lot to level it up

on which realm were you playing?

If frostmourne, it means you need to manually transfer your character to Icecrown realm (Frostmourne gets resetted every 12 months):

Select "Frostmourne - S2" as realm
