No Customer Support – Cureatr Review

I've written 3 reviews now and after I've clicked on Send each time, I get a window that says my nickname is taken - but I doubt that from what I've chosen - and my review is gone. Last attempt here. App is ok but apparently there is no customer support. All I want to know is how to delete messages rather than archive them and no one responds to me.
