Can't get my account back?

Question

Google

Someone hacked me and changed my password. I have all the account information and access to mail.ru, since I did adsense from the mail.ru address.
I want to change the password, it asks me to enter the last password that I remember, I enter it.
Next, it asks for the date of registration of the account, I choose the date.
Then he writes that a confirmation code will come to [email protected], I receive a code, I enter it there.
Next, I see on the screen that something like " We could not confirm that this is your account".
And what should I do, how to restore?
If through this form https://support.google.com/adsense/contact/cant_lo...
then he writes to me in 5 minutes by email
