Hey there TinglyCoder4777.

Unfortunately cross-region accounts aren't supported. If you're in a non-Xbox Live supported region, changing your region may cause issues like the one you're describing. Unfortunately we're unable to assist with non-Xbox Live supported regions. We're always
looking to expand availability, definitely keep an eye out in the future. Thanks for your understanding!

Hi Dradon, my name is Jose, and I would be happy to help

There are several ways to get games in Latin America while living in the US.

One option is to create a Microsoft account for Latin America. This will allow you to access the Latin American Microsoft store, where you will find games in Spanish. To create a Microsoft account for Latin America, follow these steps:

Visit the Microsoft account creation page.

Select "Latin America" as your region.

Enter your personal information, such as your name, email address, and date of birth.

Create a strong password.

Click "Create account."

Once you have created your Microsoft account for Latin America, you will be able to purchase games from the Microsoft Latin America store. To do so, follow these steps:

Visit the Latin American Microsoft store.

Select the game you want to purchase.

Click "Add to Cart".

Click "Pay."

Another option is to buy games in physical format at a video game store. Many video game stores in the United States sell games in Spanish, especially games that are popular in Latin America.

Finally, you can also purchase digital games from third-party stores, such as Amazon or eBay. These stores usually sell games in Spanish.

I recommend that you make sure the game is available in Spanish. Not all games are available in Spanish, so be sure to check before purchasing.

Compare prices. Game prices may vary from store to store, so compare prices before purchasing.

Have a nice day.

The PEPSI promo is only available to players that set their regions to the UK. Once at the Dashboard look for a PEPSI MAX promo in the bottom right hand corner of the screen. Play the game as your Avatar and finish it, then select one of the football players
(soccer in the US) and complete it as them. Once you complete both of these playthroughs (shouldn't take more then 5min) You must race the athlete and win the race. Once you complete the race you can download the PEPSI shirt (Male or Female).

I am not sure if this game support Latin American Spanish, but if it does, the description in the game of the store would say it. Did you try setting your region to Latin America and the language to Latin American Spanish?

People in Latin America are to poor for xboxes.
