WHAT IS HAPPENING TO YOU???????
I haven't logged into the game for 5-7 days and suddenly discovered that my account was blocked. I didn't give my data to anyone, I didn't use cheats myself and why would I need them here. THEN WHAT'S GOING ON WITH YOU??? I wrote to tech support, but they're just silent, and I can't call because I'm not from an English/French/German country and for me this call would be very, very, very expensive, and I'm not particularly good at knowledge of these languages. So I'd really like to know what you're doing and why.
if the suspension was billing based (could be suspended if they think the account was hacked) then the suspension may be lifted by calling swtor support
If the suspension was TOS based then you need to email swtoraccountdisputes@bioware.com
