Hi, our electricity company only billed us 65 euro for the last 10 months. I didn't think this was nearly enough and when i called them last week they said I should give them a electricity reading. However, I said it was difficult as our meter is located in our neighbour flat, I asked if they could just put up the tariff and the lady looked up what previous tennants paid the last long term tenant paid 230/ month. I asked for it to be put up to 200/ month and complained about the original payments being so low. On saturday I got the landlord to do a reading. It ends up we owe over 2,300 euro in back payments and must pay a monthly ammount of 310 euro aswell. I told them that it was bad of them to charge sooo little given how much the last tenant paid and asked them to reduce the bill and they are considering it. Is what they have done illegal? and should I insist on a reduction?
I should add that my husband called them last november to ask for a person to come and take a reading, but according to them he called and then agreed to take one and never got back to them. We have always contacted them though, we would still be paying 65/month now if we hadn't of called then

Already Tried:
Talking to a lady at the call centre and as of today her supervisor. The said they'd make an exception for me to pay it back over 24 months (= approx 100/ month) and also pay the higher fee. I said that this wasn't enough and suggested they knock 500 euro off, or give us two months free electricity- they are considering it and will let me know on friday
