How do i redeem these CRs?!?!

“2,936 pts to next tier.” You have 15 days to earn those points in order to earn those rewards. You’ve already redeemed the rewards shown below the line, which are delivered to the Gift tab in your Message Center and you must press A on the message to transfer the credits to your account. If you don’t earn the next tier’s points by November 1 then the new set of Rewards will be available for your current tier, and you’ll have 30 days to earn points to get the next tier’s rewards, and so on.

That says the 600k is your next tier reward, you need to get to tier 7 to redeem them,
