Hi Jojo, I can’t help you with contacting 505 support as this isn’t gems of war support (they are our publishers. For more info between the two see this article).. You might want to try contacting Gems of war support next time 
Either way, for this problem, you will need to try contacting Microsoft/Xbox support instead here:
https://support.xbox.com/
Try including a photo of your issue (perhaps taken on another device) to potentially speed up the process. Your account data should be saved with your Xbox account so don’t worry about losing the game.
