Brown external box broken
How do I get the cables from my external brown box altered? I have just left Virgin media after 20+ years as the price increase was untenable and so the black cables from the brown external box are now unused. I realise that I cannot totally remove the brown box ( as it's said on a previous question here) due to if I ever sell my house. However I would like to be able to get rid of the black cables which are around my window frame. I want to know if these can just be cut and rolled back into the brown box? I contacted VM on Monday and eventually was informed that someone would be in touch in a couple of days and come and do it, however I've had no contact, via either email or text so would be grateful if I can get answers this way. I don't want to do any damage to the equipment.
