I had the same problem.
I have 2 lines, not pre-paid, month-to-month, not on contract.
i stayed up on Thursday night/Friday morning, and I was able to get into Apple store website around 12:10am, however, I was not able to complete the orders, and I was given a reservation number, Apple website said that an email will be send later with the link to complete the orders.
I got the emails around 10:30am Friday morning, stating that I have until 12 noon, Saturday to complete the online order process, however, I was not able to complete the purchase, each time I tried, at the very end of the process, Apple website would display “unable to complete“ and delete the iPhone X order from my ”bag”.
I called Apple customer service rep Friday afternoon, they couldn’t find the reservation number in their system, even thought I received 2 separate emails from Apple, stating that I do have the iPhone reserved for launch date pick up.
i went to the Apple store on Friday night, on the advice from Apple customer service rep, the Apple store employee couldn’t help me, they said it may be Verizon issue with my account.
I called verizon wireless Friday night, they said my account is in good standing, so I tried to call Apple back on Friday night, they were so busy that they hung up my calls. I guess the queue line got so bad that they couldn’t handle the volume.
I called Apple again on Saturday morning, asking for help, i was on the phone with a rep for a good 45-60 minutes, he couldn’t help me, and just cold-transfer my call to the apple technical helpline, so I had to explain the whole situation again, and the Apple tech rep couldn’t help me either.
saturday noon passed, and I still couldn’t use the Apple reservation numbers that were given to me.
so I ordered the phones again, but now, both phone have the estimated delivery time in mid December.
so I stayed up on Thursday night/Friday morning for nothing.
do not trust the Apple reservation number anymore, I am keeping the emails that Apple sent to me as a reminder and evident of what not to do, when trying to get apple customer service to help me.
