If a game gets delisted from marketplace would that cause it to dissapper from my purchase...

No. A game being delisted would not remove it from your purchase history.

Hello Timmy H, my name is Oskayra, and I will be happy to help you.

Beforehand, it is important that you keep in mind that this is a public community forum, so we are players like you, we are not employees of Microsoft or Xbox, so we do not have access to any user account or check anything from the forum. All users help each other with common problems.

I am very sorry for the problem you are experiencing, I invite you to follow the following steps recommended by Xbox Support, to try to solve the problem:

If you don't see charges in your purchase history, you may be signed in to the wrong Microsoft account, or your billing information may be associated with another account (for example, another Xbox family member).

If you have multiple Microsoft accounts associated with your payment option, sign in to each account to review your purchase history.

If you know the person who used your payment option to make the purchase (such as a friend, or someone who lives in your house and uses your Xbox console), you can protect your account to prevent future unauthorized purchases. For more information, go to:

https://support.xbox.com/help/family-online-safety/child-accounts/prevent-unauthorized-purchases

If you've compared your bank statement to your purchase history and those of everyone in your family, and you still don't recognize the charge, keep in mind that you can start an investigation for a Microsoft charge on any card you have. For more information, select Investigate a charge on any card you have here:

If the problem persists, please tell me which device did you purchase on?

Thank you for your patience, I hope everything can be resolved. I will be attentive to your response. Blessings.

Sincerely,
Oskayra.

Your purchase history never gets deleted. Anything you've ever purchased will continue to show up there so you can redownload it even if it has been delisted from the marketplace.

This game would not be available through searching if it has been delisted. Games are delisted for different reasons. It could have been a licensing issue with the developers or just poor sales.

DLC for that game has been delisted from the marketplace. So it's not possible to purchase it anymore.

That game has been delisted from the marketplace so it's not possible to purchase the game anymore. When games are not available for purchase (either they've been delisted and you're trying to purchase them through the demo, or they haven't fully been added
to the marketplace yet) the price will be listed that way so it's impossible for someone to actually make the purchase.
