Am I in danger for getting banned?

Hello.

I think I've made a mistake last night and now I'm a little bit scared for getting banned.

Last night I bought two games that I wanted to play. Nintendo Switch Sports and Hogwarts Legacy. It was a great deal at first.

I know I've made a stupid mistake for buying them and I don't know how to get my money back at this point. They didn't gave me a key. They gave me two accounts with a lot of other games.

I downloaded just the two I mentioned.

Am I in danger to get banned? How can I get my money back? Should I give message to the users that their accounts got stolen?

I bought them from G2A. It was my frist time there and I thought is legit.

I'm thinking right now to delete the other accounts and the games and to buy the games again from other sites at a better price.
