Trade in status unknown

I recently traded in 2 iPhone 15 pros for the iPhone 17 pro. Both trade in phones were returned without any delays. I received 2 separate emails that both phones had completed the trade in process and to look for the credits on my next bill.

I am only receiving the trade in credit on 1 of the 2 phones. When I log onto the Xfinity Mobile website, I can click on "trade in status" on the phone receiving the credits, but there is no "trade in status" button on the phone that is not receiving the credit, so I fear that there is a bug in the system that is preventing my from getting my credit. I have talked to several different Xfinity agents and none of them could tell me what the status is, only that I had to wait to see if the credit magically appears. I have my doubts since there is no trade in status for this phone. 

Anyone else encounter this problem?
