Buy airline tickets Insel Air International

I booked a round trip flight for me and my wife from Aruba to Curacao leaving on 11/16/2018 and returning on 11/21/2018. I received an email from them yesterday stating that the return flight had been canceled and they booked me on a flight almost 7 hours later. This would make me miss my connection to United cost me 300.00 per person to change the flight to a flight the following day and cost me an overnight stay in Aruba. Around 900.00 total. I called their customer service line and they told me that I could get a full refund by emailing [email protected]. I sent the email and they replied and said they could not refund the ticket cost even though this violates article 10.2 of the carriage agreement. After several emails back and forth I contacted my credit card company, provided them all the emails and they agreed to reverse the charge. They also told me there have been numerous complaints to Visa and MasterCard about this company. I also researched it a bit and the company is in bankruptcy and only has 3 planes in their entire fleet. If you have already been screwed by this company just file a claim with your credit card provider.
