Hi Rai
Thanks for reaching out! My name is Jiyas. I'll be glad to help you today.
I can understand how frustrating it can be.
Kindly try the following steps and see if it fixes the issue.
1. Clear Browser cache & cookies.
2. Try using a different device or a different internet connection.
3. Log out and log in again to your rewards account.
4. Some users with same issue have reported that, this issue was temporary and resolved on its own after a while. So kindly wait and try again after few days.
If none of these work, I recommend reaching out to the reward support team by using the link below so that they will be to look at your account and investigate the issue.
