Just chatted online with another Apple specialist who was much more helpful than the previous one. I feel much better now. I am sharing part of her response to help all of us.
"Thank you very much for your patience! I am looking at your order now and I do see here that your new iPhone 7 is currently being prepared to ship and is scheduled to be delivered
between September 30th - October 6th* but since the order is already prepared to ship I would expect it much sooner. The order should be shipping out tomorrow or Tuesday and will be delivered within 2-3 business days after it ships so congratulations! Once your order is shipped you will receive an email with your tracking information and at that time is when you will be charged! Just remember a signature may be required upon delivery or once the order has shipped you can go to
apple.com/orderstatus and pre-sign!"
"Since you are already enrolled in the iPhone Upgrade Program you would not be able to enroll again unless this order was returned." (This was in response to me asking if I could enroll a pickup phone in IUP also - no need to now).
Looks like most of us should see movement in next 24 - 48 hours!!!!
* I had original Oct. 4 - 10 dates but they were changed when I chatted with Apple Specialist on 9th and explained I had work trip starting Oct. 3.
