I've had a smart meter for quite some time but the monitor stopped working, so I phoned E-ON to ask if they would replace it but they couldn't because that monitor was now obsolete so I would have to have a new meter and monitor.This was fitted, but the traffic light system didn't work, so I phoned them and instead of just sending out a new meter, 2 men in 2 vans arrived!They told me that because I am a low user, the traffic signal won't change from green, so a wasted visit by them.
