Billing info keeps getting declined

i put a new card on file for my Apple Music! When I wanna use it to start a new subscription on Apple Music it says my payment was declined! So it asks me to put my CVV number! It lets me put it in but after I put in all the info, it brings me back to the Apple Music screen and says payment was declined due to billing info! There’s nothing wrong with my card and billing! This is so frustrating
