I just went to process your challenge club signups, hit a hiccup. Is this your first signup? I can't find any record of you in the relevant retail clubs for any of the listed games, so this needs to be done first. You'll have to signup for each individual game in the retail club.
You also list yourself as having completed other tiers, but there is no record in the leaderboard. Have you had a GT change?
If you have any questions on what to do, please ask and I can walk you through it.
Gonna delete your signup for now as it can't be processed, but we will sort it out together.
