Tales from the borderlands and pre sequel

I own a disc copy of Tales from the borderlands, how can I get the heads and skins on the pre sequel? There is no place to sign into shift where I believe it should be says coming soon.

IIRC there is SHIFT option in Tales, but you should submit a ticket to SHIFT Support. If any rewards are missing like heads&skins or new loot, support can add them to you account.
