I'm really confused by Virgin's strategy with broadband speeds.
At the start of the year they were offering Superfibre 50 for £32.25 per month.
Then, just 4 months ago, they made a big song and dance abut 'ultrafast' Vivid 100 being their standard entry-level speed.
But now they have introduced Vivid 50 (originally as a budget product) at £33 per month as their basic speed.
Where is the logic in any of that? I get the impression they just make it up as they go along.
