Unable to link card to App Store

I have problems with the appstore the fact is that for some reason I logged out of the appstore account and when I logged back into the account, he asks me for a password and I write everything correctly, but after that he asks me to link a number or card since you don't support my number, I linked a card in which all the data and information are correct, but your the database gives out an error, I thought the problem was in the bank and linked another card, but everything exactly gives out an error. please help me with this issue. I am very unhappy that such a large company as apple gives out such errors. I think you will answer me if not, then I will just spread this error on the Internet so that you will definitely notice
