Problems with Pipex continue, I am afraid to say. I was originally with Toucan, who were then absorbed by Pipex and in turn by Tiscali.
My broadband connection went down at Easter. No ADSL signal. Several (very expensive) telephone calls to the helpline resulted in a technician failing to call round one evening and then a week later calling round to confirm I had no ADSL signal. After nearly four weeks and half a dozen telephone calls I was told by the Pipex call centre that the only option was for me to wait in for a morning or an afternoon for another technician to sort out the problem, which was presumed to be at the BT exchange. Well - I have a day job and, in common with a large proportion of the population, live by myself, so that was not possible.
Instead I moved my account to PlusNet who restored my ADSL signal on the promised day without fuss, and provided a telephone line with free weekend and evening calls for just over half the monthly cost of the Pipex package. No brainer.
Pipex/Tiscali give the impression of a struggling company. Their rates and service are not competitive any more.
