they must help you if you have spend money or time into the account.
Doesnt matter if you bot or not.
Keep contact with support, ask them what to do

dont give up on that .. it might take some time..
After that give them all the info they need.
Example's :
- Copy of youre id card
- police letter with prove you realy lost youre acc.
- numbers cellphone where uridium got bought with.
- first nickname
- first email
- payment options
- USERID <- very important
... after all of this you get youre account back, but please think about it..
If the hacker did this trough you're comp, he wil do it again.
Good luck! if you need any help, contact me
