I don't mean to be rude, so I apologise if it comes off that way, but you should really try to write in proper English so others can understand and possibly help you... Also, posting a thread on the High Level Forums will do absolutely nothing for you, other than attract trolls who'll just respond with useless crap to this thread.
Firstly, read
this
thread - "How to boot/lock your account". It should be able to assist you in gaining your account back quickly.
Secondly, contact @JagexSupport on Twitter, and a JMod (or CH??) will respond to you soon, and hopefully get it locked for you.
Thirdly, in case the hacker has any other information of yours, you should change your passwords for emails, etc so that you can remain secure.
And lastly, once you have your account back, I'd recommend reading
this
thread - Email and Social Media Safety.
Good luck getting your account back, and hopefully you haven't lost anything.
