I haven't abandoned aglimpseoflondon (in case you were worried), it was an enforced temporary arrangement courtesy of BT.
Finally and after hours of calls and chats they sent an engineer who could confirm we had no line at all. Oops he said. Despite a few hours earlier been told it was all repaired and working well. Another visit and rewired somewhere in the street, communication has been restored. Only problem now is how I am going to manage the massive speed of 2mbs from my restored broadband.
Wishing you all a great New Year and a fabulous 2017.
