The Engineer Has Finished!
We have now a stronger signal and hopefully the engineer (whose name was Ben) has found all the faults and finally finished fixing the problems.
I we have had very interesting day yesterday with Ben having to drive back and forth for the Exchange to us, checking the work he was carrying out. I thought he had gone off at one point because the gap was so big. But he eventually returned very frustrated apparently he had to check 40 connection junctions before finding the fault on the 41st. He was pretty well put out by that 40.
So, hopefully we will be back to as normal, well as the now normal, as we can be today.
