I booked a Chocolate Tour through Groupon with Celebrity Planet for June 30th. However, due to bad weather conditions I called the company a day before and rescheduled with them for October 6th at 5PM. At 12 Noon on the 6th, I received a phone call asking where I was for the tour. I told the director that I had expressly booked the 5PM tour on the 6th, not the 12 Noon. Anyway, when I called to find out what happened, I was told they had made an error and the 5PM tour was sold out and we could not go on it. I was then offered a date in January to reschedule. The operator had asked me why I failed to confirm the change via e-mail, which I was never told had to be done. Is it the customer's responsibility to do this or the tour company?
