Making missed payments

I have been having a tough time and have missed some payments. I am now in a position to start catching up. However I can’t find any way to make payment on demand. How do I do this?

Go in to your account, then
payments & statements
Click on Top up balance

Hey John, Scudo is right and that will work if you have a payment method set up. If you don’t have one set up, head to ‘account & tariff’ info and you will see the option to set up new payment details there.
