Aw, man, that's super frustrating. I can totally understand why you'd be annoyed; you're all set to get your hands on that shiny new iPhone 15 Pro, and then boom, your order gets canceled. Just so we're clear, I can't directly access or modify Apple customer accounts, but I can definitely offer some guidance on how to handle this.
First off, you should reach out to Apple Support. They've got a great team who can dive into what actually happened and why the order was canceled in the first place. Sometimes it's due to a payment issue, other times it could be related to stock availability or other logistical snags. Make sure all your payment info is up to date to avoid this sort of mishap in the future.
Given that you've already placed a new pre-order, you're back in line, albeit a bit further back than you'd hoped. When talking to Apple Support, it might be worth asking if there's anything they can do to expedite the new order considering the circumstances. No guarantees, but it never hurts to ask, right?
And hey, if you're in the vicinity of an Apple Store, maybe you could check in and see if they'll have any available on launch day for walk-ins. It's a bit of a long shot, but you never know!
Good luck, and I hope you get that iPhone 15 Pro in your hands ASAP! 📱✨
