So why are BT making this kind offer?- Well I suspect it isn't to make things better from consumers, it is for themselves. Seems like they are giving themselves an extra 2 years to do something they were being forced to do earlier.
I'm on the receiving end of this dither, on a good day we get 4Mb up, 150Kb down, with no prospect in sight of improving our EO line. For some bizarre reason our line is about 3Km long, where there is a perfectly good fibre enabled exchange 200m the other way. What really sticks in the throat is the lack of economical alternatives, and being marooned on full price line rental, and full price 'ultimate' broadband ADSL. If they could even do the decent thing and make that half price, or £1 per Mb, it would help my mood. However, I'm pretty sure I'll still be grumbling away in 5 years time on the same rubbish service, after this followed by others at 6 monthly intervals are rolled out.
