Welcome to our Community and thanks so much for your first post on our forums 🙂
Sorry to understand that you've had some issues with your cabling and isolator cable - this is certainly something we can get sorted out for you and we should be able to get this sorted out by popping you a new one and some extra cabling in the post for you totally free of charge.
If you need a technician to pop round and help you out though, there may be a charge.
I've located your account from your forum information so I'll pop you a quick Private Message so we can go through security and get some in the post ASAP for you.
Look out for the Purple Envelope and pop me a reply when you can.
