@BlueLou I contacted customer support via WhatsApp over lunchtime and provided a link to the "360 upgrade to get Sky Sports +" thread on this forum, which says that a recontract is not required for the TV 360 upgrade. The response of the agent was "The reason the previous advisors were asking you to change your package is due to the current tv package you have is no longer available with Virgin it is stopped very recently so if you are looking to upgrade your TV box you have have to make changes to the package.". When I asked how my current TV package affects the software on my TV box he said "The reason is if we are upgrading the software of the box we will have to first make changes to the TV box in our system after which we will be able to upgrade it, So to make changes the package you have is currently unavailable due to which we are unable to do it.". He then also said "I would request you to kindly wait for a a month as we are working on upgrading the box in a swift way, I would request you to contact us once again to get the update for the same." although it doesn't seem clear whether the TV package would still be causing a problem then.
