Hi, I am Van. I'll be glad to assist you today.
To begin, kindly verify the status of your claimed rewards using the link below.

If the rewards appear on the list, you can redeem the code or the redemption link by clicking the View Details option beside the reward. If the reward is not on the list and you have stated that the points have been deducted, I recommend submitting a report via the link below so that the rewards team can review your account in detail and assist in resolving the issue.
