Two destinations were cancelled and one was changed before sailing. When my travel agent called to ask for a credit or to cancel the reservation, we were advised that it was too late since the last payment had been made.
I ordered a package of 12 x 1L bottles of water before sailing. They were charged to me twice. I called the customer service line and spent over an hour on the phone with them. They reimbursed me for both and advised that there was a package on my account already. This package was apparently later cancelled due to non-payment which we only found out when we checked into our cabin and I called to ask why it was missing. They said that it had been cancelled and the price was higher once on the ship.
We scheduled an airport transfer from the ship to the airport at the end of the cruise. Shortly before flying to San Juan our return flights were changed. Rather than flying out before 12pm, they were now late in the afternoon. Our travel agent called Norwegian's customer service to cancel the transfer and was advised that we should go to Guest Services once we'd boarded the ship. After boarding the ship, we went to Guest Services and they refused to cancel the transfer and the latest transfer was still too early. I talked to two supervisors and a manager and they all refused and did not offer any flexibility or changes.
