Confirm whether TNT is down: One more reason why you may not be getting the activation code if the TNT website or app is down. If the server is not working therefore it can’t relay your code.
Unluckily, there isn’t much you can do in this case. Keep on checking sites like Down Detctor or the official TNT social media pages for details on when the application or website will be back. Only then you will be able to activate TNT drama.
