Update:
I was really, really hoping for some codes I could redeem in-game that would give me my missing coins, add-on content (which, in my case, should have equaled more coins), and maybe even a bonus code that gave me something for my trouble.
Instead, I get this e-mail:
This is in regard to the issue you've reported to us where you have multiple missing purchases. Honestly, after looking this over, I think this is likely linked to your PSN account. I Suggst here you talk to Playstation about an account related issue. One single missing piece of content is a one-off, multiple of different types is account related.

Once again, thank you for speaking with our specialist department at EA help. Should you have additional questions please feel free to reach out or add them as an addition to this case. Thank you again and fair thee well until we speak again!
So, no, EA was unable to help me. I'm supposed to call PS Customer Service now and spend untold hours trying to find some thread somewhere on "social media pages" about my issue. Oh, and check out the EA Forums... I think EA should be checking out the EA Forums - especially the Technical Issues forum...
Not happy.
