Worst customer service I have ever experienced. My wife and I had a vacation booked to Hawaii, I had to cancel and had paid for cancellation insurance. What a joke, they make it impossible to get a refund. Then we needed a revised itinerary for my wife. After a total of 4 hours on the phone, most of it on hold, I finally got a representative that could barely speak english, charged me another $250 to change my wifes itinerary, and still cannot get a copy of the revised itinerary, even though I have given them my email several times. Will definitely use a travel agent in the future. Stay away from Priceline.
