Re: Battlefield 5 deluxe Pre-Order and Origin Access Premier
You may need to contact EA support, otherwise you can maybe try going to your Order History (found under my account), finding your Deluxe Edition purchase of Battlefield V and refunding it from there (there should be an option next to the specific purchase).
By doing so it'll likely refund your payment for the Deluxe Edition but since you now own Premier you will keep the deluxe edition anyway as it is included with premier - this means any skins from the deluxe edition will also stay in your possession.
