So my sister (carrier: T-Mobile) had reserved an iPhone X in store and went to pick it up on launch day. She informs the rep that she has a store pickup order, but she wanted to sign up for iUP instead. A few days later, she didn't get the refund posted on her account (I got mine a few days ago since I had done a similar pickup / join iUP plan). I told her to check her order status, since if they processed a refund, it will show up on there. There was no indication that a refund was pending. Today, she got an email from Apple telling her that her order is still awaiting pickup. She has a few more weeks to pick it up, otherwise the order will be cancelled. I told her to go to the Apple store and get this taken care of with a supervisor or manager, but she's asking me if she can just wait it out and let it automatically get cancelled or call Apple (probably to avoid the crowd at our apple store). I don't have any knowledge or experience in this personally, since I haven't really dealt with Apple beyond my launch day pickup experience (which went fine). So I figured I'd ask the community first before I reiterate / change my original answer of having her go to the Apple store.
