Firstly, have you been able to get in contact with TeamYouTube, Creator Support, or created any other threads here on these forums to try to resolve this issue?
 
If you have, then we wouldn’t want to duplicate any work already being done else where. If you have any other forum threads about this hijacking, then please close all of them except for one to avoid duplication.

Can you provide screenshots of the messages you get when you try to recover the Google account? Recovering the Google account is a critical first step, so we’ll want to assist with that first.Were you monetizing prior to being hijacked?Is it OK for the email support team to contact you by the email you used to create this thread?Since you cannot follow basic instructions, I’m afraid I won’t be able to help you. Please read my original comment and let me know when you can follow all of the instructions I noted.
