Still a customer as I have no issues (touch wood) and the next best supplier for my needs would cause a monthly increase of 150% in my bill.
However I wouldn't recommend them to anyone in the current state. (Nor have I ever done so)
Oh I would, and have done so. But I advise people of possible issues with new installs and if they have a history of line issues they might want to go elsewhere. But I've been a PN subscriber for over 2.5 years now and despite being out of contract am happy to stay. They had a wobbly period in the first half of '15 but otherwise they've been giving me full speed 24/7. For £23 pcm that's a damn good service.
So yeah, their CS is poor (a lot better if you go via the forum staff) but if, like me, you almost never need to talk to CS the service is good value for money and very effective.
