Hacked Account 120909-001628

My friend had his account hacked on the 9th of September, support is waiting for a serial which my friend replied with a few days ago, the serial was provided in the original ticket also.

Any chance of getting this sorted as it has now been 1 week where he has not been able to access the game.

RESOLVED Thank you guys
