Carnival Cruise Lines review: Misleading information on fcc expiration resulting in loss of fcc

My two FCCs (R60BN8 and R60BF8) were confirmed to be extended until 30SEP2023 when I last contacted Carnival customer service. However when I contacted the customer service (resolution center) today on 23SEP2023, I was informed that my FCCs have expired and the extension did not happen or at least not annotated in the account.

Given that the annotation to my account is not visible to me to verify its accuracy, or if the customer service rep that extended me till 30SEP2023 failed to make an annotation to my account, left me feeling cheated. I was also informed that I forfeited my FCCs that totaled to more than USD1,100.

I was excited to be bringing my parents on this short cruise, but after experiencing this with Carnival cruise, given also that this is my first time cruising with them, has left incredibly bad experience with them. Carnival will never be the company that I will consider for any future cruises and will not recommend such company for friends and family. I hope the management has visibility on this complaint and remedy the situation so not to lose more customers/ potential customers.
