Guns of Glory: The Iron Mask

it was in interesting game

I'm still unable to surpass level 60 even though I've completed the task as the terms and conditions require, multiple times, over multiple days and weeks however nothing works. I get a blue checkmark on it periodically but nothing else. I've contacted support multiple times and nothing.. Help me?
