Hey, we’re incredibly sorry this happened. The text was incorrect. We’ve corrected it for future Vault flash offers on PS4.
If you contact us at Support we will send you the Gems we advertised in the Vault Offer as it wasn’t our intention to mislead anyone.
Ghaleon is correct, we’re not permitted to sell premium currency (Gems) on Sony platforms at a discounted price so we replace Gems in the Flash Offers with Gem Keys or VIP Keys.
This article has the full details along with links to the correct support form you’ll need to contact us by and instructions on how to find your receipts so we can send your missing Gems:
