Netflix gift voucher?

I intend to register there and my question to you.

But only want to top up with a gift voucher, that means buy on the fuel card, eg enter 15 eur code done.

2 question)

Let's say that I did everything this way and that I don't feel like 3 or 6 months later, and I simply no longer buy and top up the card, I'm still obliged)

Reason for gift voucher, my bank account number does not want to give in the net.

I simply entered "Netflix voucher".
