I use VirginMedia, which were good when they were NTL but the service has gone downhill (along with the speed) since becoming Virgin
It's still is NTL they bought virgin mobile which gives them the rights to use the Virgin logo for a duration of 30 years. Branson excepted a mixed cash/shares deal that gave him 10.7%. What irritates me is that people mistakenly believe that Branson has control of the company and all the problems are his fault for not doing any thing about it.
And I know of many people that have had as much trouble with NTL with or with out the name change.
That's not all, there are rumours that usage caps and phorm will be introduced soon.
Phorm (who have a shady past http://en.wikipedia.org/wiki/Phorm ) also applies to BT and Talk Talk.
There is a rumor that Virgin Media are distancing them selves from phorm as phorm say that Virgin have signed up. But Virgin claim "Virgin Media has signed a preliminary agreement with Phorm to understand in more detail how this technology works but we have not yet decided if it will be introduced." (so more than likely yes here's a link to the Vigin Bull http://www.virginmedia.com/customers/webwise.php)
There is also the question is this legal? After all prostitution and "pimping" is illegal in the UK (which is what the ISP's would be doing).
I pay £37 a month for a 20Mb (which I do get on the odd occasion depending on time of day and the server) with unlimited down/up load connection.
If they introduce a usage cap then it looks like I and a few others will be looking for a new ISP, as there are cheaper alterantives.
If I do leave Virgin then I will have to run the gaunlet that was labled "NTL HELL". Where people who canceled their sub-scription kept getting billed and threatened with court actions and the bailiffs.
