Sharing my experience -I am traveling 6.3 Adriatic and that cruise is spot on- no balance, correct OBC. The following 6.10 Croatia was fine until recently when my FCC was removed leaving a balance owed and removing my OBC for a back to back.
Like most, multiple submissions and requests for a call back. One call back never had an agent, one was on me for missing, and on Monday got to speak to someone. After 30 minutes she came on to let me know her teammate would work my account next and complete. As of Thursday nothing so we will see.
i agree with everyone on the communication- this is disastrous for the brand and requires regular and transparent updates. That’s owed to clients and the many people working including onboard staff, our TAs and call center agents.
