Once logged in, go to 'My Account', "Edit My Details" to check you have the correct 2FA (Two-Factor Authentication) mobile number on your account. This will need to be linked to a device that you have access to while you are withdrawing your funds.
Once you have confirmed that the 2FA number is correct, go to 'My Account', "My Funds" and then select "Pay into Bank Account".
On this page, you can check the mobile number has updated, enter the amount you wish to withdraw and select your reason for the withdrawal.
After the withdrawal request has been confirmed, a transaction reference number will display. Save this reference number and follow the on-screen link to pay the requested funds into your bank account.
