How can I add a new payment method on Apple

Problem with purchases and subscriptions through the Apple store. The American card I use has expired, and I got another card. I only need to enter the number of the new card in the payment methods, but this is extremely rude of you. In short: I have several purchases and subscriptions through the Apple store. The American card I use has expired, and I got another card. I only need to enter the number of the new card in the payment methods, but this made me so angry that I canceled all subscriptions and purchases. Makes no sense. In this situation, YOU DO NOT ALLOW ME TO DOWNLOAD ANYTHING, ABSOLUTELY NOTHING, TO MY MOBILE, EVEN WHAT IS COMPLETELY FREE.

Oractically, my mobile phone is blocked until I enter the number of the new card! I WON'T! Allow me to normally download what is certainly FREE! Otherwise, I will not even enter the number of the new card to continue subscriptions and purchases!

extremely rude!
