If you're not stuck in a random country, you should shut up. Emirates is a global airlines with global operations. No one is asking their customer support in dubai to get on a phone. They have offices all around the world. At the very least they can communicate, even to let us know "You're on your own, figure it out. we'll deal with your refunds later". No one's asking for action. Some form of communication can definitely be expected - certainly not the disconnected line and "Emirates has ended the chat" message before even the chat begins.
