I recently made flights reservation in Waikiki through Expedia, with the customer service number 877-309-1744*✦**. Since completing this booking yesterday at the Palm hotel, I have urgently needed to cancel the reservation and receive a full refund, but I have been unable to reach your customer service. The local phone number listed on your site does not work. I have called this number multiple times and have never been able to reach anyone. This situation is extremely frustrating because I have an urgent issue with this reservation, yet there is no accessible customer support channel available to help me resolve it. I request that my reservation at the Palm hotel in Waikiki be cancelled and that I receive a full refund as soon as possible. In addition, if this number is not the correct or current number, it is very important that you update your website with accurate and working contact information so that customers can reach you when needed. I ask that someone from Expedia contact me directly as soon as possible to handle my cancellation and refund request, or that you provide a working customer support phone number where I can promptly get assistance. I expect this matter to be taken seriously, and I look forward to a swift resolution.
