Agreed! Its almost impossible to get through to Princess - even to make a booking. I was waiting in the UK (to make a booking, not just to answer a question), after over 90 minutes waiting the phone rang, and then someone put the phone down! In the end I booked through a third party.
Even trying to call in an evening, the response is no quicker and I have never waited less than 90 minutes. Terrible customer service!
