Issues With the In Game Store

I've had a problem for the past ~5-6 months, where most packs in the store end up not showing up for me. All of the packs that cost actual money show up, but packs such as the 500cr relic packs, chromium packs, and character troves never show up. I tried 3 months back to get help with this problem to no avail, but I am unable to purchase the 8,000 shard shop currency trove atm, and would like to have this problem fixed so I could actually use the in-game store again. This problem persists on the PC client as well as on mobile, with only the webstore being usable (troves and chromiums don't show up on the webstore though).
