Don't think you can get to speak to google unless you are a paying customer
If you can get access into here (official google forums)

create a topic for unable to access your gmail account, you won't get a direct response from google initially, but the top contributors can pass things onto google employees for them to check it out
I have seen many topics about not being able to access accounts on here, so it should be possible
