I've been onto my ISP who contacted BT. Apparently the engineer had added some notes to the call which talked about there being a terrorist threat, flood or fire problem. You've got to laugh... it was a bit windy yesterday but no flood!
Just as in the other thread, linked by Robertos, the engineer was from MJ Quinns.
The ISP, obviously Plusnet, is working on getting an expedited appointment.
