Touchstone Media review for DHL Express India

This app is simply bad. After installation, the app does not show up in the shipping tab. Tried all kinds of ways to get it done, but always fail. When I contacted the DHL for the tech support, the girl who answered said DHL do not have or have develop such an app and simply hanged up on me. I wonder why Shopify have not take the developer of this app to task. Or is it just a fake app? I assume is it. The previous DHL app on the Shopify app store was working fine until Shopify decided to discontinued it on April 1st this year for no reason.
