My Iphone 5c has some of my apps updating for 3 days, they are black & it says waiting. It will not let me delete them or I cannot go stop the updates

I never gave my phone authority to update anything. When I go to the apple store, the apps that are trying to update are not even listed . I cannot use these apps, It won't let me delete them either. What should I do? I already tried turning my phone off
