To make renewals impossible, giffgaff also documents removing your saved card: Account > Payments > Remove this credit/debit card, and confirm.
- • Renewals charge a saved credit/debit card or PayPal account — a continuous payment authority rather than a Direct Debit. If a payment ever needs stopping at source, the card-issuer route is explained at /answers/what-is-continuous-payment-authority.
