Ordered new phone, keeps pending then disappearing

Last Wednesday I ordered a new iPhone to upgrade an existing line. I received an email saying we’ve received your order, we’re working on it, an order number, and that another email would be sent once the order was confirmed. I saw the card I used to purchase have a pending charge. Then heard nothing. Yesterday, afree unsuccessfully going back and forth with the AI chat, I was able to get a human via chat. They had no record of my purchase and when I then checked the card used for purchase, I did not see a pending or posted charge. Felt weird, but no harm no foul and figured I’d just reorder. Places the order last night, same thing - initial email received and have a pending charge on my card. I’m hoping to hear an update that it’s been processed soon but feel like I may have the same thing happen. What am I doing wrong?
