Wrong system selected on pre-order survey now I can't get Loot

I was initially going to buy the Xbox one Deluxe Diamond Edition but had to go with PS4 because the store didn’t have Xbox one available. Since I filled out the survey for Xbox one, it won’t let me update or change where my rewards or VIP purchases go. In the FAQ on SHiFT, they state that I will be asked what platform I want my items to go after I purchase, but that is not the case.

I have it on pc and ps4 when you make a character on ps4 it should go to the shift mailbox and it wilm get redeemed on whatever platform you grab it through the mail system on.

I also have my vip rewards on both platforms did you link all your accounts on shift?
