Updating and downloading apps

I’m unable to download and update apps on my iPhone 11 it says something wrong with my billing every time I try to update or download I’ve checked everything signed in and out of my Apple ID like literally everything I keep trying to use my card that’s on file but i don’t know what the problem is if anyone could help that would be great! Also yes the wifi is great and I have storage to download it jus won’t let me cause of the billing ??
