I had a orc warrior max level named Gsapas on Frostmourn and my account just dissapeard, can we do something about it?

when did you make that character?

Your join date is "March 10, 2021 ", so if you have made that character between 10-March-2021 and 14-April-2021 it means you were playing on "Frostmourne Season 1", which ended on 14-April-2021

In that case you can manually transfer him to Icecrown realm:

Select "Frostmourne - S1" as realm

Thank you it worked
