Answer 1

This is because your bank is declining the payment.

1. Check that you're entering all the correct details
2. Take a look into your bank last movements to see if there is any declined payment
3. Try with other credit/debit card or other payment option

Answer 2

If its an Indian credit Card :

Heroku mentioned

India issued credit card verifications Effective October 1, 2021, new Reserve Bank of India (RBI) regulations state that no automatic recurring payments may be processed using India-issued credit cards without an additional factor of authentication (AFA).

Because of these new regulations, Heroku is currently unable to verify and process payments with India-issued credit cards for Heroku Online customers. Enterprise India-based customers are not impacted.
