> premium Google customer paying for a service

And what is the best way to become part of such group while at the same time paying as little as possible?

Also, if for some reason Google decides to simply block/ban my account as a whole (so I can't login), how will I be able to contact them in order to even say "hey, I am that premium customer"?

(serious questions, I rely on Gmail and have always been afraid of simply losing it)

Take a look at the cheapest storage option. It's something like $20/year 100GB. I signed up when my storage needs exceeded about 10GB. Your mileage may vary.
