Problem with payment

Hello. I have a problem with registration of my credit card for apple store. I have registered my card last year for purchasing in apple store, I haven’t any problem, I paid for apps during all year. And now, I decided add my husband to family music in apple store, and I saw that system shows me a mistake with my card. It says that my way of payment has not been confirmed, I tried past the information about my card again, but again I see this mistake, I tried to add a new card, but I can’t do it too. I want use your services and different apps, but I can’t do it. Please help me with this problem.
