Etihad LOST our Passport at Check-in Desk

I had the most shocking experience that caused so much stress and trauma in our lives. We gave the etihad staff member our passports at the check-in counter at Abu Dhabi International Airport. Our luggage was sent through and she handed us our boarding passes and only my passport. We immediately told her 1 passport is missing. We called the manager and air port police to the desk and told them to check the cameras, but they were only interested in covering their own backs! They did not allow my husband to fly. He was stuck in the UAE and had to go through such unbelievable ends to get a temporary passport to travel, let alone book another ticket and spend so much time and money trying to get home to his family. They eventually found his passport at the airport and have not even contacted us to apologise or compensate. I have never been treated so badly in any country that I have travelled to. Such unprofessional behaviour. I would not recommend anyone to fly with this Airways. Utterly disappointed in their ethics and honesty
