Thought I'd share my Renewal experience
I recently renewed with Sky Sports/TNT/Movies, phone & 1GB broadband for £60. A major faff though as that was the deal I was offered in "my Virgin Media" when I logged in (being 2 months from contract end it was called something like early renewal special offer), they cancelled the renewal order a week later saying I needed to call, was then quoted £97 and that I couldn't have the £60 due to a "price mismatch", after complaining and being forwarded to a UK call center they sorted the discounts on my account to honour the £60 deal (as I had a email confirmation of a deal saying that).
If you get an email saying you've got an exclusive renewal deal in My virgin Media its worth logging on and having a look, just be prepared they might cancel it if its a good deal, but stand your ground and state that you want the deal you accepted honoured. I was paying £46 before and also got Netflix! which is obviously a crazy deal that I knew I wouldn't get again. Probably spent about 1.5 hours on the phone in total.
