Hi Roppa2002,
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 that you're unhappy with the installation. In terms of the distance, the engineer would have checked the levels to ensure these were correct so that won't really make much of a difference in terms of the connection. As for the cable hanging, this would be a health and safety concern. Lets see what we can do to get someone round to make this safe.
I will need to confirm some information with you to pass security so I have sent you a direct message to allow us to do this with you in a private space. If you are 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 are on a mobile/tablet device then instead click on the little circle icon in the top right then select 'Messages'. 😊
Thanks,
