Disconnected Early and Massive Billing Increase with Home Move

I arranged a home move with the service/connection due on 29 December 2025, but today (28 December 2025) my broadband has already been disconnected, leaving me without internet to organise the remainder of my moving logistics the day before the scheduled move date.

On top of that, I’ve just noticed my new contract monthly charge is much higher (£31.99 to £72 monthly for M500) than my previous monthly price despite no changes to my package and insisting to remain on the same service over the phone (despite upsells). I wasn’t expecting this, and I’d appreciate a clear explanation of what changed, and confirmation of the correct ongoing price.

Can a VM team member please advise:

1. Why the service was disconnected early (before the move date)
2. How to get service restored immediately / ensure the move goes live on 29 Dec as planned
3. How billing/credits are handled for downtime
4. Why the monthly charge has increased so significantly
