Hi Rui Fisalia,
I understand how confusing this is, especially since your Microsoft account region and billing address are already set to Singapore and the same type of purchase worked previously.
This error may occur if another region setting involved in the purchase still does not match Singapore. Please check the following:
- Open Settings > Time & language > Language & region, then confirm that Country or region is set to Singapore.
- Open the Microsoft Store website, scroll to the bottom of the page, and confirm that the selected store region is Singapore.
- Sign out of both the Microsoft Store and Roblox apps, restart the device, and then sign back in with the same Microsoft account.
- Make sure that no VPN or proxy connection is active while making the purchase.
- If an Xbox profile is connected to the purchase, confirm that its location is also set to Singapore.
Please also note that Microsoft account funds are region-specific and cannot be transferred between regions. Therefore, any remaining USD or HKD balance may not be usable for a purchase processed through the Singapore Store. Changing regions repeatedly is not recommended, particularly because Microsoft may restrict another region change if the account region was changed within the last three months.
You can review Microsoft’s official guidance here: Change your country or region in Microsoft Store
If all settings already show Singapore and the error continues, the purchase will need to be reviewed by Microsoft Store Support because the forum cannot check the account’s commerce region or billing configuration. Please contact Microsoft Support, enter Incorrect region when purchasing Robux, select Get Help, and then choose Contact Support if available. If the Support Assistant appears, type I need to speak with a live chat agent and follow the prompts.
Please note that this is a user-to-user support forum. Moderators and contributors, including external Microsoft employees, cannot access account billing records or change regional settings on the back end. Thank you so much for your understanding.
