Character gone

Good night, Warmane team.

A long time ago I had stopped playing, but now I want to go back. However, I remember that I had a character on two servers, Lordaerone and Icecrown. However, today when I logged in, I saw that my Icecrown character disappeared, when I select the server, it appears that I have a character on that server, but he does not appear. Can you help me?

when did you stop playing here?
and what level were those characters?

I stopped, I believe that in 2018, the level was 80
