WotLK Account Hack and Recovery

[Owwca46]

Hey!
Recently I remebered my old account I made on this server probably about 5 years ago and enjoyed playing very much! But today I decided to go and check it out for the very good old times you know. And I got surprised with incorrect password and all my toons deleted and lost in darkness.. I don't know when this happened, I checked last account activities and noticed there were some logs from different ID, changing my password every now and then.
Now I wonder.. Is it even possible to recover something that happened more than a year ago? Will I be to reunite with my chars ever again?
For info: I had a lvl 80 warrior and druid.
I don't really remeber warriors name, but Owwca is my druid babe <3

Please any help or info about it would be appreciated!

Greetings!

Server was wiped since then, all of those characters and accounts are long gone and there's no more compensation for those.
