Since our energy company went bust we have had nothing but hassle out of EDF,, for months they kept claiming our smart meter isn't talking to them.
Anyway, they sent a demand that we increase our payments to £380 a month, the wife spent 4 hours on the phone with them yesterday, it turns out they seem to think we have a day/night system, the house did have one 15 years ago but we ripped them out and modernised and it has never been a problem with any other energy company until now, they pretty much accused the wife of lying about her not having a second reading on the meter.
I would suggest by the time she has finished with them they will regret implying she was a liar lol
