Having been another of the BE there punters who didn't want to end up with Murdoch wares. I went with a cheap deal with my mobile provider and oh my had a I wished I had not!

The initial service was ok. Varying pings and speeds, but it was relatively stable for the first couple of months.

I then reported a drop in upload speed to 0.02mbs
I then went through around 20/30 tech support people who just washed themselves of the problem trying to say 'We don't support upload speed'

Horrendous tech support, weeks wasted with script led idiots.
Attrocious Customer service, wasted days trying to log complaints, only to get passed back to a tech support idiot.
Unusable complaints department. Having given up trying to have a telephone conversation with Complaints. I emailed in through the website. Got the obligatory Automated response of a call back within 48hours and 2 weeks later am still awaiting that call. Have logged subsequent complaints and also had no response.
Emailed Ofcom and emailed the cancellations department, I recieved a call the same day and having berated the tech support so much, I was given waiver of all disconnections fee's, given a MAC code and left them IMMEDIATELY!
