Twitch Acc hacked?

Can't log in because my PW and my username has been changed, I also got mails that people from Thailand, South Korea etc. Have logged in on my Acc.

All Reset PW Dinger do not work, the email with my username does not arrive and the support does not answer me. (got the default mail where you should confirm his identity with IP address etc, but nothing else)

So, if the question is, if your account was hacked: Yes…
