Pending How Do I Change "serveradmin" password using "Client based query login"

I have a TeaSpeak server, But I bought it from a website so I don't have SSH access. Some guys are attacking my server and deleting server groups. They changed "serveradmin" password. I have a "client based YatQA". I wan't to change "serveradmin" password. How can I do that?
