M. Fell. This must be the worst company in UK for customer service. I have sat in the house all day waiting for an engineer who was supposed to be here between 10.00am & 2.00pm, never turned up and no text or e mail to say why. Tried several of their phone numbers but they were only to leave meter numbers. I used to be with SSE for ten years & no problems. I was transfered to OVO who seem useless. I did not want a smart meter, know too many people having problems with them. One was put in and apparently has not been working. I was told I did not need to read the meter with these so haven’t. I received an e mail to say I needed to pay an extra £22.40 per month to avoid going into debt. However when I checked I was £784 in credit!! I did what everyone else should & got most of it back, they insisted I left £182 in as that’s what I pay per month. They must be the most inefficient company in the UK!. Think I will delete the one star I have shown, not worth it.
