You're extremely wrong, I contacted EA via live chat, someone answered immediately and I didn't even have to justify that I had done the necessary takedowns, the person just activated the reward on my account and that was that. Good and fast customer support experience.
Sorry for the delayed response to this, for future reference to anyone else experiencing this - contacting EA Help through this link will allow you to go through steps in claiming the cosmetic that you may have been unable to aquire.
Dev team over at DICE are aware of this and are working to resolve it so that you don't need to hit up the support team too, sorry about that!
