In Rocket League, the Cristiano Ronaldo-themed items, like the "Cristiano" car, became available through special promotions or events rather than being tied to a player's rank or payment status. If you didn’t receive the Cristiano items, it could be due to:
1. **Limited Time Event**: The items may have been part of a limited-time event or promotion that you missed.
2. **Platform Restrictions**: Certain items or promotional content may be tied to specific platforms or regions.
3. **In-game Requirements**: Some items might require completing specific challenges or taking part in events that weren’t completed.
4. **Tradeable Items**: If the items were tradeable, it’s possible to miss out if you didn’t engage in trading with other players.
5. **Account Status**: Ensure your account was in good standing and eligible for promotional rewards during the promotion.
Check the official Rocket League announcements or forums for details on the availability of items or any events you might have missed. If you believe there is an error, contacting Psyonix support could clarify the situation.
