I transfered over to Economy Energy in Oct 2017, after going on a comparison site which said it would save me £200 a year to move. I was paying £84.11 a month for gas and electricity and paid off a balance of £69.04 at the end of the contract in Oct 2017. I was give new direct debits set by you of £42 a month for gas and £14 a month for electric. This seemed all it was promised to be and a big saving going from £84.11 a month to £56 a month. Over the year I read the gas meter 3 or 4 times. Tin Sept I get a letter from them offering me discount tarif for the following year and the' number to ring' I thought great I'll do that. After waiting an hour on the phone I gave up. Then I went on the website onto the live chat. Same problem again. 45 minutes I waited to talk to someone and then they told me I needed to ring the 'number'. So I tried again and was just told someone would ring me. Great, but I am a teacher and can't answer my phone most of the time during the day. They rang twice, but I was unable to answer my phone both times. So I thought this is ridiculous and changed supplier. Then I get a text from them saying I owe £561.61. I'm thinking how could I have possibly accumulated such a big bill when a direct debit is supposed to spread the cost over the year. With my last supplier I owed £69.04, which tells me they have done that. Luckily I am in a position where if this amount is correct I can pay it, but I’m sure for some people it would be devastating. Do not touch this company with a barge pole. It's disgusting that you can tempt people to change to you with promises of a lower payment when in fact it's about £220 more than the year before. Then I had a phone call from a very rude member of your staff who demanded payment of the balance. This is a few hours after recieving the text. Giving me no time to check my bank balance, do some sums and recover from the shock of such a big bill. She would not listen to me, she kept talking over me, she was not interested in anything I had to say. She just kept saying are you refusing to pay. I kept replying 'no' I'm not refusing. I asked to speak to a manager and she said she would ring me after 5pm and hand me over to a manager, but no one rang me. You can not reply to any of their texts or emails and the only way to complain is on their website, where there is no evidence of you contacting them. They are supposed to reply to emails with 5 days, it has now been 6 and I haven’t heard from them. A lesson I have learnt the hard way, do not touch companies with low ratings, they are deserved.
