In case of any problems or issues regarding payment, make sure that your Google Play account is linked to a valid credit or debit card.
If you can’t bind the bank card to your account (for example, you have 16 digits instead of 18), you can go around this problem by using PayPal. Create a Paypal account, link it to the card and add the PayPal account to Google Play
If you encounter other problems when you subscribe to the app, please contact customer support: firstname.lastname@example.org
