Non resposive touchscreen iPhone X

Hey so i have a iphone X and it was in my pocket while i was fishing and when i put it in my pocket the touchscreen was working and when i went to use it 2 hours later the touchscreen wont work but it will turn on and off with the power button. I would try a force restart but the volume buttons are broke as someone scammed me on ebay and eBay refused to cover me, and i dont have the money to replace the volume buttons right now. I have tried unplugging the battery from the phone and replugging it in and turning it on but that didnt work. Does anyone have any idea??
