Hi,
Just thought I'd conclude what happended here. You were right. Even though the webpage says re-contract for £107 and keep everything you have this not true. Going to the next step and viewing the pre-contract there is no sign of TNT Sports. In my case there was no mention of my second TV box either. As I was getting nowhere with retentions I opted for this offer. The actual contract says TNT Sport has been removed but the extra box is showing.
I am disappointed. In the past VM have been great to deal with and offered good discounts when you call but not this time. I was hung up on during one call as I wouldn't agree to an offer that included a mobile SIM i didn't want and retentions no longer seem to have any power to help. I would cancel and move on but I actually like the TV box and the broadband is solid for me.
Good luck everyone with your dealings.
Ian.
