Do you have confirmation that VM are despatching a replacement co-ax? I ask because any amendments or alterations to your cabling are usually actioned by tech visits - there have been a few posts about "ordering longer cables", but they usually involve offshore CS agents who are "mistaken".
And no, you can't use B&Q or any other well-intentioned DIY fix here - the correct solution is to have a non-fault tech callout if you want to move any VM kit in your home or alter cable lengths.
That comes at a flat £25 charge and either a faults agent or forum staffer can arrange.
