I had setup the 2-step verification on my on my uninor number but it expired for some reason and there is no way to get it back...

Now I remember my password but not able to access gmail.

When I filled up recovery form, Google is asking some question like when you have created this account and the same like this which I don't remember and I need my gmail at any cost because it was my permanent address...

Is there any other way to get my account back?

Please help me...
