How do I see the virtual card number for a card that has been deleted?

I used my Bank of America card through Apple Pay to purchase an airline ticket through the United phone app. This flight was cancelled and was "refunded to the original purchase method." However my BofA account never received the refund. United Airlines will not give a credit because it has been refunded. However, the last four digits of the card where it was refunded do not match my card. Confirmed it was purchased with the card.

To complicate matters, I switched cards on my Apple and deleted the above card, along with the virtual card number assigned by Apple. QUESTION: Is there a way to see the old virtual number associated with the card so that I can confirm if this is the "card" where United sent the refund? If I add it back, the virtual card number changes each time. I am still missing $400+ from the transaction. Thank you!
