Customer service advice to create US account. Useless advice from mindless people. If you need a key, find another seller.

Hello.
The product page mentions that you will receive a key based on what is currently available in stock, either it is going to be EU or US key.
Therefore you received a US code (based on stock availability) with instructions on how to redeem it.
Both EU or US titles are identical and can be played from any account on your Swtich.
Thanks.
