Have already done that and waited nearly an hour for an answer. Hung up rang the same number but pushed the option to book a new cruise and was answered in 1 minute 34 seconds. There is a surprise. Was lucky enough to be speaking to somebody who had an awful attitude, very rude and wasn't interested and said it was my credit card company fault and nothing to do with P&O. Then she politely said (NOT) there is nothing more I can say with regards to this matter and hung up. Awful customer service and P&O are very near to the bottom of the barrel in how they treat their customers. Certainly think they should look at attitude of some of the staff they are employing. But no doubt if you pay peanuts you get monkeys.
