If you just came back 2 years ago, the stuff in your storage would be character lock on aquire. Same to the armors that you were wearing if it was in your inventory all this time. It would remain character lock on aquire. Once you either equip it or take it out of storage it is already locked on you.
If you already sent a ticket and nothing can be done, then nothing can be done. Sorry to say. If its honor/valor armor gears, you might as well disassemble them to obtain some valor/honor points to get another set. If i am not mistaken it would be a 30% return of the actual cost of the armors.
Once again i am sorry but there's nothing that can be done if even the gms said so.
Btw, if you say not fair, how so, everyone is already experiencing this long since the database update. You're not the only one facing this, everyone else is as well. Also life isn't fair, since when has life been fair to people? This is how things are.
I wish you the best of luck to gain/regain the items you want.
