I managed to get the traffic management moved up to today and the traffic management people turned up, but Openreach didn't

A few phone calls and they did eventually get here at lunchtime much to the annoyance of the traffic people who were just sitting outside my house for three hours.
Lots of discussion, complaining at the last Openreach people (as in fact they didn't really need the traffic management) and the ONT got installed where I wanted it. The Openreach engineers were really helpful and dragged 50 meters of fibre up and round through a wall, a ceiling and down into a cabinet.
It still isn't working, as there is something up with the registration of the ONT. It has a steady sync light, but gets a CHAP authentication error and Zen who I just spoke to thinks it isn't provisioned properly. Have to wait until tomorrow.
So getting there!
