Thank you both for the encouragement. 20 minutes into the initial hold and conversation, the guest agent tried to tell me that -I- changed the promo type and that's why it was messed up. 😒 After I pushed back and said, No, the website did what it did and I didn't -choose- anything, I was put on hold another 25 minutes. Thankfully at the end, everything was fixed and corrected to what I had been shown at the original booking.
From now on, anytime I book with Celebrity in the future, I'm going to take appropriate screenshots. 🙄
