Hi Vanpoon,
Thanks for taking the time to contact us via the Community. It's lovely having you on board with us in the Forums. ⭐
We're sorry to hear you're needing to move the external box. This isn't something that is always possible. We'll need to book an appointment for you, the team will come to access and if it's possible, they'll be able to complete the work.
I'll need to confirm some information with you to pass security so I've sent you a direct message to allow us to do this with you in a private space. If you're using a PC/Laptop then you can just click on the little ✉ at the top right-hand side of the page to access your inbox. If you're on a mobile/tablet device then instead, click on the little circle icon in the top right then select 'Messages'. 😊
Thanks,
