We were forced to transfer to OVO after the collapse of Economy Energy. Our initial dual fuel offer from them was £75 pcm. A few months later it was increased to £117. We recently received info on their app saying our annual usage suggested electricity would cost £18,000 p.a! Kayty, from OVO admitted this was an error. Another member of staff, Erikah, informed us we had not been charged for electricity as there was a read dispute which had now been resolved, and we now owed them over £400 for unpaid electricity usage. We had received no information about this and had been giving monthly meter readings and paying our direct debit. We are trying to transfer away from OVO as we have lost all confidence in any figures/information that are presented to us by their ever changing 'team'. They do not deserve one star but this is the lowest available option
