Chargebacks for games

Been looking to buy Animal Crossing New Horizons and get it refunded/chargebacked if it was possible.
Does chargebacking G2A or CDKeys still work? It's been a while since I've done any form of chargebacking/refunding so I'm not sure as to whether they respond to them now or what.
If the sites above don't work, what would be the cheapest way to get a key?

Thanks.

Nah g2a doesn't work anymore
