I already filed two reports regarding this matter. Included in my reports is the video where I was not able to redeem Roblox Digital Cards but was able to redeem 7-11 Gift Card,
These are the responses of their two rep.
I understand that you’re unable to redeem a Roblox gift card. I know how important it is for you to redeem your desired reward. Allow me to help.
After thorough review, you have encountered an issue with redeeming rewards because you appear to be attempting to redeem an item from a country different than the one you have earned points from, which is a violation of program policy. Please be inform that you should only be redeeming rewards in the markets where you have earned points (your market), this is because offers and rewards varies between account, region or market. Please ensure that you are not using a proxy or VPN service that may obfuscate your true location. This case will be closed, and we are unable to offer any additional assistance on this matter

We understand you are contacting us because you are unable to redeem Microsoft Rewards points due to the SMS verification process. After conducting a thorough review, the possible reasons why you received an error when redeeming your points may include the following:
The use of Voice over IP (VoIP) numbers. In order to redeem your points, you will need to provide a working non-VoIP phone number. This requirement is outlined in the Microsoft Services Agreement. We do not require the mobile phone or non-VoIP landline to be yours. If you do not personally own a mobile or non-VOIP number, you can use a family members', a friends', or neighbors' phone for this purpose. We do not share phone numbers with third party companies nor use it to contact you.
Redeeming an item from a market outside of your current location, which violates our program policy. The availability of offers and rewards may vary depending on your account, region, or market. Therefore, it is essential to ensure that you are selecting rewards that are designated for your particular market.
To further assist you, we kindly request that you refrain from using any proxy or VPN services that may obfuscate your true location. These services can interfere with the accurate determination of your market and can result in issues with redeeming rewards.
No clear answer why we cannot redeem Roblox Digital Cards. **
