Your child is critically ill with cancer. It’s the worst news you can get. But to make the situation even more awful, you struggle to afford the care they need. So, when someone tells you a foreign sponsor can help raise the money, you’ll do anything. You make a video: your child begs for help from strangers online. But it comes to nothing. You wait and wait for the cash from the donations. It never comes, and all the while your child is fighting for their life. In this World of Secrets podcast from the BBC World Service, BBC Eye uncovers the shocking truth. Released from 15th December.
