Haven't touch the game lately, all I ever did was change my ign and then bam, permanent suspension.
I went to submit a ticket and explained my side, and I did disclose which "third party apps" I'm using, they all use Valo's API though so I know I'm safe and didn't do anything wrong. And I also included that I reinstalled my OS(downgraded 11 to 10).
Luckily, an actual person responded to me within 6 hours. They said that my account was compromised? Just changed my pw and they lifted the suspension.
If it's important, I'm from the SEA server. All of my tickets were always answered by a person.
I suggest that you should spam them with tickets until an actual person answers you.
