Give me a minecraft gift code account for free?

You can't get minecraft for free unless it's a reward in a contest.

To get a gift code, you actually have to pay for it. Gift Codes aren't given oyut free, someone pays for the game, and instead of downloading themselves gets a code to "gift" the game to somebody else.
Nobody is going to buy the game for you

Just go to a torrent website, (like piratebay) and download it from there. No gift card. No money. No surveys.
