Just FYI I've merged your posts into one place to avoid duplicates, as this can get confusing for other members
If you'd like to get in touch with our Member Services team you can tap 'help' > 'Ask WattBot' in your account and send them a message.
The 'occupier' bill you received will be covering the energy used between when you took over the property to when you switched away to your chosen supplier.
We have an FAQ about making a one-off payment to cover this, which may help?
I also checked this out with our Member Services team - they've let me know they sent you an email on 14 August and again on 29 August to let you know how to contact us and to request further information. The email subject was "FOR INFO: We're on the case", if that helps you find it? 🙂
If you could reply to their email they'll be able to help further and make sure this is settled for you.
