I have traveled with GCT, OAT, and on their River Cruises a total of 33 times and never had any problems. I was promised a refund after 5/1 for the cancelled trip that was supposed to start on 3/28. I called a few times and was promised that the money would be credited to my Mastercard, but I keep receiving bills with interest, but no refund so far. I am desperate and will take further action if I do not get any result otherwise. I am so sad, loved to travel with them.
