[2020] I haven't received crystals for 25% Chest of Crystals.. no idea what to do.

I have bought "Chest of Crystals 25% more" few days ago. Till this day I haven't received the crystals that I have paid for. My fund were taken, the transaction registered in Apple.

1. I have tried to contact EA. I've created a case which now says "waiting on player". However when I enter it I don't see anything except buttons "Resume, Attach files, End Case"
2. I have tried to "Restore Purchases" via App but that didn't work.
3. I don't want to do chargeback as I'm afraid I might get banned and I won't be able to contact with EA again.

I'm not from USA/Canada so I cannot contact them "live"

Any idea what else I could do?;/
