Hello all,
So sorry, should have updated this thread .
When in the village shop on the Monday after we had first had the problem on Sunday afternoon/evening I discovered that half the village seemed to have the same problem, some had even been without landline since Saturday! The suppliers were various, but I suppose that whoever you switch your phone provider to, it comes down to BT/Open Reach who manage the actual physical service and connections etc.
Aaaaanyway, we were eventually back in the land of the telephonically connected by Wednesday afternoon.
Which reminds me, I must contact my provider and ask if we are going to get some sort of discount, after all we were without a usable landline for 3 days.
