eSIM swapping issue, HELP!

I have an iPhone 14 Pro that's completely broken and won't turn on, so I ordered an iPhone 16 Pro, which just arrived today. I went to a local Xfinity Store, and they told me that the only solution was to activate the 16 Pro with a new number (6664) and then contact Xfinity Mobile Tech Support to swap the numbers, after which I’d need to cancel the new line. However, there's a problem: on Xfinity.com/mobile under "Devices," it shows the numbers have been swapped, but when I try calling my old number (9662) from my wife’s phone, it doesn’t go through. All the calls I make from 16 pro display 6664 instead. I’ve spent a whole day trying to get help from customer service, but no one can resolve the issue, and it’s incredibly frustrating. I really don't know what they did with my number, I would really appreciate if any of you know what is going on.
