Reiter says O’Leary changed the cancellation and refund information after Carnival canceled the Greenland portion of their cruise. Reiter, a regular reader of Consumer Rescue, suggested to all of O’Leary’s disgruntled customers who paid with a credit card to file chargebacks based on the original refundable terms and conditions of the cruise excursions. The general manager said that on that particular cruise, O’Leary had booked 180 Carnival passengers on a different tour, not the iceberg excursion that Reiter had booked.
