Lost character.

I used to have a character called Evomrtav on Frostwolf MoP server. About 7 months ago I transfered him to Sargeras but then I stopped playing. Now I came back and I dont see the Sargeras server or my character. What happened and is there a chance to retrieve my character to Frostwolf?

lmoa, bad choise dude. Sargeras has been closed and Staff actived Free transfer from Sargeras to Frostwolf but now it is too late. I am sorry
