Bought the wrong REQPack thought it was Arena Pack

I went to GameStop yesterday to buy a Arena REQ bundle but instead I bought Warzone REQ Bundle. I didn’t know I bought a Warzone REQ till now so I was wondering is there a way I can switch it with Arena REQ Bundle with Xbox. I was really excited to open some Arena REQ but now I’m worry.

Have you scratched off or redeemed the code yet? If the code is underneath one of the scratch panela and it hasn’t been touched, you could try taking it back to GameStop and seeing if they will trade. If it was printed on a receipt they probably won’t though
