My whole experience with EDF has been a nightmare. They took over GNE who has made some mistakes In billing. I appreciate there will be issues. However I gave them all the correct information numerous times. I was then told my monthly debit was increasing from 99 pound to 617pound, and I owed 1600 pounds. They kept estimating my electric usage to 4x what I used and gas to 3x the amount. When showing them correct figures they kept doing the same. It took 6 months to resolve. Over 30 hours of waiting on phone calls, being hung up on by rude incompetent staff and writing emails. I revieved letter after letter causing stress as I could not afford this stupid figure they made up. When I eventually did the work for them and raised it to the CEO team they even initially tried scamming more money. When back calculating costs I owed, they were using the inflated price per unit of today's date which was more than double that I used at the time (BE CAREFUL AND CHECK WHAT YOU ARE PAYING) finally they admitted I owed 300 pound and my monthly debit was 117 pounds. After 6 months of my time I managed to fix it. They do not value thier customers at all, they arranged dates and times to call back so I would be able to answer as I work shifts and would never call, thus wasting more of my time. Absolute joke regarding thier customer service.
