We purchased 8 certificates onboard the Joy last month and the cost is shown on my final invoice. The certificates are not reflected in my account or my husband’s. I sent a general inquiry and was told they were “deactivated” and I needed to contact Cruisenext staff. They have been completely non-responsive. A PCC trying to help me book sent them another email on my behalf and copied a supervisor. It’s been crickets, I’ve sent a few additional emails asking for status of their review. Has anyone ever heard of this? We’ve been on 4 NCL cruises, bought certificates every time and never had a problem. I don’t know where to turn, other than at some point disputing the charge with AMEX for undelivered goods.
