Missing rewards after purchasing BP?

I already contacted support before anything else, and I was told to post on the forums and that they’d “forward my issue” - 6 hours and still no solution. I was around tier 67 when I made the complaint. I purchased the Premium Battle Pass (without the bonus 20 tiers) and received all of my rewards except for 400 coins and only got one legendary loot box, which I should have earned two. Has anyone else had this issue and found a solution yet? Or will I have to wait it out until support does something?
