You can only change your bank details when you are making a new Refundid request.
To do so, at the end of the flow when your bank and card information pops up, click on ‘Add a refund destination’ and input your details.
Please note, Refundid cannot reverse refunds that are sent to the wrong bank account so please ensure your details are correct before placing your refund request.
If you require any further assistance, please submit a request here.
