How do I claim future cruise credit from my canceled cruises on a new booking?

[bnbeyer]

I've had two cruises canceled that I had paid a certain amount of deposits and payments that I believe are supposed to be future cruise credit.  (I'm not including the on-board credit that they'd offered for rebooking.)  I'd like to book one of the offers I've gotten using that future cruise credit, but I can't figure out how.  The website wants me to pay another deposit.  Anybody know how?

If you don't use a TA to book then call Carnival. When I rebooked a canceled cruise today I had to pay a new deposit for the reservation then after it was reserved the agent was able to apply the future cruise credit to the booking and also add the onboard credit bonus. I wasn't happy about having to pay another deposit, but the PVP said that was the only way she could book it.

Thank you.

I've just got off the phone with Carnival.

Since Carnival already gave us back partial refund  last month, They have transferred all info & FCC from old cancelled cruise to new one in Jan.  No need to pay new deposit, just price difference by Oct, but offset by OBC later:
