No. I just did everything on Apple's site. I never fucked w the Citizen's One account I just get billed on my CC.
Yeah it auto populated it in my Apple Store app.
What country do you live in and how did you buy your phone? Did you go to the Apple Store, have a credit check and had them put a credit card on file?
If for whatever reason your phone isn't showing up it has to be an error on Apple's end. I've never heard of people getting 24 month financing without being on the IUP.
