I Want To Connect Orbitz Customer Service For Hotel Cancellation

My Orbitz hotel reservation/itinerary number is 855 2015 621**, and I recently made a hotel reservation in Waikiki through Orbitz yesterday. Since making the booking, I have been trying to reach your customer service by phone. The local phone number listed on your site does not work. I have called this number multiple times and have been unable to reach anyone. This lack of accessible customer support is extremely frustrating, especially because I have an urgent issue with this reservation that needs to be resolved: I need the booking to be cancelled and fully refunded. When the only phone number provided does not connect, it leaves customers without any way to handle urgent problems like mine. If this is not the correct number, it is very important that you update the site with accurate and working contact information so that customers can reach you when needed. I request that someone from Orbitz contacts me directly as soon as possible to address my cancellation and refund request for this reservation, or that you provide a working customer support phone number where I can promptly get assistance. Clear communication and reliable customer service should be a priority, and I expect this matter to be taken seriously and resolved as soon as possible.
