BGB fail, fail and fail again ...
British Gas supply my business electricity to me. Three years ago they had the best rate, so I let them install a SMART meter. Year after EDF underpriced them, so I moved. Last year back to BGB ... BUT, they are "unable to read the SMART meter" due to the status "G4S pending SIM card activation".
So the supplier that installed the original meter is now unable to read it. I wonder who is reading it?
What a mess - the £390/meter number is no surprise given this level of competence.
