When a monthly charge fails – for example if the card is blocked or expired – the account is automatically blocked. You cannot start new charging sessions until the debt is paid.
How do I pay my debt?
Open the app and go to Menu > My payment methods.
Check that the card is valid and not blocked.
Replace the card if needed (see the article Adding, changing or removing a payment card).
Retry the charge via the app, or use the payment link feature. A link will be sent to your email and you can pay your debt via a web form.
