Unable to install the game & updates. HELP!!

Yesterday when I try to play my game, it shows me there is an update. So I start installing the update, at 155 MB the installation stopped, no matter what I do it won’t start. Then I uninstall the game to see if I can download it. This time I won’t even be able to install the game. I have contact Xbox and tried everything they told me to do, reset Xbox, check my storage… after all that, still won’t install the game. HELP!!
