Hi Martynf89,
Welcome to the Community and posting your comments 
My apologies for the TV issue you've experienced on V box. I have been looking into this and have seen some issues on one or more boxes in the home. I would like to arrange an engineer out to help with the situation and check out all boxes in the home.
I've sent you a 'Private Message', you can find this by clicking on the little purple envelope near the top right of the page.
Take care.
Ben
