Experience Using Chase Travel

It was on my list to try using Chase Travel more for flights since the benefit for purchases awards 5x points (since 2021).  My most recent itinerary had a cancelation where I was sent a partial refund, however, after several weeks the refund had not posted to my Chase card account.  I reached out to Chase with the information and was told I needed to contact JetBlue - when I called JetBlue I was told a refund was issued to a card ending in numbers that were not mine.  That's a problem.  

I found out that Chase Travel uses virtual numbers to complete transactions.  Even though I have a receipt showing the charge to my (correct) card number, Chase Travel used a virtual number to confirm the reservation.  My impression is this should be resolved internally by Chase Travel once the refund is issued back to the travel partner.  When I called, the nice agent confirmed they had received the refund but 'hadn't got around to it yet' to process the final.   This seems pretty dubious to me - how long does it actually take them to process these when received?  I asked the agent and was told that eventually they get to them but anyone can call sooner to complete the process.

My recommend: increase awareness when using 3rd party travel sites for both customer service and any reservation issues
