Purchasing premium with gift card

I’m curious whether or not I can purchase premium with a gift card and if so, what would happen if I paid for say a month and when it was time to automatically renew, I had no payment method on file and my gift card was gone? Would it just not renew?

Hi, we are using the official Google Play Store integration. You can read everything about the gift card here Geschenkkarten-Angebote, verfügbare Anbieter & Verwaltungsoptionen – Google Play.

It should try to renew automatically.
