Sony has nothing to do with the game servers for Mortal Kombat. It isn't a Sony-published game. The game is published by Warner Brothers Interactive, and you need to report server problems to the support team for the publisher (http://www.warnerbros.com/help/customer-service.html). Even if it was a Sony-published game, no one from Playstation customer support monitors this forum. If you want to report a problem with a Sony game, then you have to contact Playstation customer support by phone or live chat, during business hours (https://support.us.playstation.com/app/contact_options).
