To modify or delete an existing payment method, kindly follow these steps:

1. Access the "WALLET or Payment Method" section.
2. Select the desired payment method from the list of currently registered methods.
3. Choose "Remove payment method" or "Edit card" and then confirm the action by clicking "Save" on the pop-up. Users may also update their payment method during the ordering process.

It is important to note that a Tgo account must have a minimum of one payment method at all times. If you wish to delete the only payment method linked to your account, please add a new payment method before proceeding with deletion.
