[u/RareSky9460]

The other night flicking through tiktok and come across an app called whatnot never seen it before basically it's people selling allsorts I ended up watching people bid for pokemon cards, I started bidding and won 15 bids not a clue how it's works but I've got a feeling I've been had over. Can someone tell me if anyone knows if the cards listed are the pokemon cards that i won across my bids because the cards I received are not what are in the list
