Absolutely rubbish company , I was an sse customer on prepayment meter which was here when I moved in 29 yrs ago so just kept it . 2 weeks ago went to top up but meter wouldn’t accept my key so phoned them they said need new meter ok that’s fine . BUT they wouldn’t fit it in till I had under 1 left on my meter REALLY . I finally got an engineer to come out put a new meter in topped my key up from 20 credit it wouldn’t accept fine so I thought . But I was WRONG meter had no emergency so went and topped up surprise new key and meter not accepting my key ! Phoned again to be told they gave you wrong code you have to wait an hr and go back ! I DID BUT SURPRISE still not working so phoned again ( this time had less then 20 p) to be told my meter hadn’t been registered although I spoke to 3 different people and they didn’t suss that . Was told to go again to put different code in was now sitting in cold snd dark but had to wait another hr ! When I mentioned that was told lucky you’re not waiting 3-4 hrs bloody rude . After my 6 phone call and 5 trips to top up finally had electric meter that was working . There people are rude couldn’t care less and are totall incompetent. I will be changing suppliers asap and if anyone is with Ovo I suggest they do same
