I got 4 callbacks on my case. The first one, as I explained above, asked me for proof and to wait 24 hours. They also sent me an email telling me how to reboot my phone and the app.
The second and third callbacks both resulted in hangups from the EA side. Both initial reps indicated there would be a 45 second to a minute period with no sound, then hold music. On the second call, as soon as the call was transferred, the call ended. On the third call, I waited on hold 3 minutes, at which point a woman answered, but obviously could not hear me. I stayed on the line anyway, for about 3 more minutes, until she hung up on me.
The fourth callback, I finally got a positive result. The lady listened to my complaint, asked me some questions, put me on hold a few minutes, then returned and credited my account with a Mk 3 Carbanti.
Moral of the story: Keep trying. Eventually you'll get a rep that has some clue of what they're doing.
