23 years (and counting) of hell from SSE/OVO. If 'minus stars' existed, this would be a score of -100%. We are stuck with a 55 year old malfunctioning Radio 4 teleswitch meter and a single phase semi-functioning 'smart' meter because OVO has sent incompetent engineers out at least 5 times each time failing to remove both systems and give us a functioning 3 phase meter. My mother went to her death in 2022 with fictitious unprovable bills c.£8k against her account. In the space of 3 years since taking over her house with the two malfunctioning meters, SSE/OVO has overcharged us more than £12k. Two unresolved Energy Ombudsnan complaints later, the second live one still being active, we are no further forward-now my mother's 'debt' is against her estate, and we can't sell the house with this matter unresolved. SSE were incompetent bullying crooks who used an elderly lady to make money (on her DD, on which she never defaulted), and OVO have failed to fulfill the remedies set out by the EO, and are now holding us hostage in an unsaleable house with two meters, neither of which functions or meters correctly. Together, they have irreparably damaged the mental health of two generations of my family, including mine. The side effects (not being able to afford heating because of extortionate bills) has meant that we couldn't socialise in the house, the books have gone mouldy on the shelves, and my mother retreated to two rooms before her health collapsed completely. These companies have used the metering situation as a licence to extract our money and waste huge proportions of my time and energy trying to communicate and negotiate with them. I have been on the phone to either OVO or the Energy Ombudsman several times per week since August 2023 when OVO took over from SSE, for up to 5 hours... Nobody would believe how much damage they can do to their customers' lives if they hadn't experienced something similar themselves.
