Lost gmail password


New Email
Hi Ive lost my old gmail password in an accident last year 2012
All I know is my username but no getting anywhere
I tried one of the guys online but he has disappeared with my money (yes silly me)but again no getting anywhere
I can prove this account is mine with my passport and drivers licence (both have photos proving its me)

Can anyone give me any advice please? I know you cant call Gmail in Australia

Thanks Simon
