Happened to me on an account I didn't use for a couple of years. I used the same IP, login, password, recovery email. Nope, 'we can't verify it's you, try again later'. Later I tried, and tried, and tried for a few weeks, still the same. I gave up, transferred all services linked to this email, with some back and forth with their support. Then, after a couple of month of not trying I was finally allowed in. The moral is this: google can't be trusted with such serious and vital service as email. They can freeze your access to an account and offer no way or support to let you back in.
