HighTower - sounds familiar... I ordered Pipex Anytime on July 7th and despite numerous e-mails from them over the last 4 months saying it will be live in "5-10 days", still nothing. Whilst the broadband itself is fine, the rest of their business seems to be a shambles.
However, I called them again this afternoon & they tell me it's going live today - I'm not convinced but we'll see.
I asked about the contract start date & they confirmed it was July 7th.
I too used to recommend Pipex but not any more.
