Where do I start! Like many others I was moved to EDF. Never experienced anything like it. My account was in credit, received email saying my dd was being changed to £2,685 per month. Nearly had a heart attack. Phoned customer service, their initial response was that’s a lot ! Before you think I live in a mansion, I live in a 3 bed semi detached. Spent 2 hours on the phone trying to sort it out, we a pensioners and don’t even receive £2,685 a month. One agent told me I was below average usage, another told me I was above average usage! My direct debit was changed to 177 per month. After 6 months, which is way too long to receive accounts, I was £1,200 in credit. They refunded me £576 pounds. I didn’t want the refund, so I paid them back £500. This is we’re the problem really gets interesting. My direct debit then increased to £285 per month, so again I spent 2 hours on the phone asking why. I then agreed to pay £200 per month, after much puffing and blowing I was told my monthly amount would be £233 I asked why when I had agreed £200 the reply was I would pay £200 dd and the £33 would come off my credit, by this time I was totally brain haggled! I didn’t argue any further,because I was banging my head against the wall. 2 days later I received email saying because I had £500 in credit my dd was being reduced to £2 a month I.e £24 a year, another 2 hours on the phone, we agreed at the end of it to change it back to £200. Still way too much. Checked my account no direct debit for September showing, back on the phone. Apparently because I was £500 in credit they didn’t take the money, but would start in October. I then asked to speak to someone who could explain how they worked dd out. After a lot of hot air being spoken, I was told I was paying too much, and would end up in credit! I have asked for a quarterly bill, which they have agreed to do but I am not holding my breath. I did ask if they had shares in mental institutions, because they are doing their best to make sure I end up being sectioned…..no doubt the saga will continue. I am definitely changing companies as soon as things settle down. Sorry this is so long..
