Summarize this customer ticket in less than 250 characters:

On XX/XX/2019 we purchased a service with NAME_1 XXXX ( also known as XXXX   NAME_1 by XXXX XXXX ) for our group of 23 people to go to various islands and snorkeling activities out of XXXX. The bases of the dispute is that NAME_1 XXXX took us to 1 island only and did not follow thru with the itinerary that had been planned out. Most of the conversation was over the phone. At the end of the day with much confusion NAME_1 XXXX charged my card {$4400.00} for services NOT rendered. This is the cause of the dispute. I tried dealing with NAME_1 XXXX and they were not budging on refunding us partial payment due to not following the itinerary that had been planned. So I then went to my Credit Card Chase Sapphire Dispute Department to resolve the issue. After many, many phone calls and months of dealing with this dispute, our Credit Card has sided with NAME_1 XXXX word over ours on what went on that day. Basically NAME_1 XXXX has continuously lied about the events that day and even said they gave us a credit which was also another lie. I have spent so much time on this and can not believe that we as customers with a very good history have to deal with our Credit Card on this level. \n\nThere was another large group lead by XXXX XXXX on this excursion who also felt they were not given what was promised. That group also disputed the charges and was refunded the money by their Credit Card company. \n\nOn the attached PDF pages 12 -14 give details of what went wrong that day.
