Game not working

My game crashed while playing on my phone. I uninstalled multi times cleared cache an data. After multi tries I tried to install the game on a different phone. Same kind I have. When I went to install game on said new phone I get a error code 971. Anyone tell me why? As we know support email seems to be a bot sending back emails. Never seems to be a real person. They now have quit emailing me back. So I'm forced to ask here
