Hacked Channel

Ok, so I had my email hacked. The email was makewaves7860@gmail.com. The hacker then transferred ownership of my youtube channel to his email, and then he removed me. So I have no access to the channel anymore. I recently regained access to my account makewaves7860@gmail.com, but I had discovered he had become the owner of my channel and removed me. I have no access to the channel, but now I do have access to my email. He transferred the channel to the email tehkruz@gmail.com. What do I do? I have tried emailing your support, and they haven't been of any help. This is the second time this has happened, but last time my channel wasn't transferred, therefore I could get it back. Plz help I think he may sell it. Plz help ASAP.
