firstly, i have never been able to purchase tickets from held itineraries where the itinerary was not build on .bomb. .bomb can only issue held itineraries built from the website. If the itinerary was on hold from a call center, they always have the message saying that this itinerary cannot be purchased on .bomb, please return to your original booking source to purchase the ticket. I hold many reservations and am very familiar with this.

Also to add on, i have found Chase's Online Secure Message center to be very useful. If you select your subject as a rewards inquiry, it gets directed to a special team in Chase that solely handles the mileage plus credit cards, in my experience, they seem to know their stuff and you should seek help from that avenue. Cos once Chase transmits the transaction to M+ for the miles to be credit, it gets done in 1 week for EQMs and 1 statement cycle for RDMs.
