Error in character window

Hello. I deleted the character with the nickname "Sxrrxwhvze". to create a new one with the same name, but it gave an error *name not available*. This is a character on my account, but I don't see him anywhere. I only had one character, and in the list of worlds I can see "Icecrown (1)", but in the character selection window itself it is empty. He was literally stuck somewhere. Please help me remove it completely from my account. Thank you!
