Ill try and find that out for you, as I'm not familier with the playstation billing system.
Are all your purchases on the same account on the same platform?
The reason I ask is there was a lot of confusion when cross progression went through, as to what content was carried forward.
Specifically:
Content - how does the merge treat the 500 pack counter?
The 500 Apex Pack counter will not merge. Your counter will be carried over from your highest level account.

And
Do my purchased packs on my lower level account still count towards my heirloom?
Your pack counter would use the primary account for the number of opened packs rather than combining them from all connected platforms.
