I can not activate in the App Store, ask for a bank account number or mobile phone

Hello, I encountered such a problem: I can not activate in the App Store, ask for a bank account number or mobile phone, I enter the data, however, I am told that there are not enough funds, but there is money. I tried to enter the number of another card, it also does not work. I guess it's because quite by accident I received a paid application for free, it was a glitch of the App Store, I'm ready to pay for it.

I have an iPhone 6s.

Thank you in advance, I hope for your help
