Hi this will help you logging in, heading to "My giffgaff", and then to the "My payments" tab. There you can change the following details: * Your saved credit / debit card details * Your auto top-up preferences * Your recurring goodybag preferences * View your order history Make sure that this information is correct at all times or you may not receive emails from giffgaff (e.g. if you forgot your password) and the SIM cards you ordered. Good luck and hope this helps
Hi, if the payment is for goodybags change iv at https://giffgaff.com/profile/payment-details but if you mean for the phone itself whoever ordered the phone are responsible for all the payments as the credit check was done on them
