I need to downgrade too - just spoke to an advisor who said I should pay extra 50p to keep the same bundle - who train's these people???
Eventually I got through to them and they told me I would be on a reduced TV and Broadband package (100mps) instead of 200mps which I have never had anyway and the cost of the 'BASIC' package (TV BB & Telephone) would be £63 - I'm currently paying £77.20 not much of a decrease but it's something I suppose. These packages are getting way out of my price league so may have to consider freeview package.
