We had a similar experience a few months ago. The Princess promotion was ending on a Sunday that we wanted to take advantage of and since our travel agent doesn't work weekends, we had to call and book with Princess directly. Got everything booked with no issues. We just happened to check the website the day after, and saw that our cabin that we had already was AVAILABLE. Called Princess again, and found out that our reservation had been cancelled. No email, no notification, no nothing. If we hadn't gone onto the website and looked, we would have assumed our booking was still good.
