What can I say about this company. Well, ever since I joined them they never once got my bill correct (per month). Even though I was putting in my energy usage into their app like they asked me to. Then I was told they'd rectify the mistake thr following month but I needed to pay the current bill or it would put me in 'bad credit if I didn't pay'... I left them on Sunday 30th April after 8 months of incompetence. I sent the the readings in writing and photographic evidence. I phoned them 3 days after sending the readings and they confirmed they'd recieved the readings and photos. And said they would produce a bill to these readings and that would be my final bill with them and how sorry they are I'm leaving. I had to bite my tongue and stop myself from having a go at the person I was talking to, as it isn't their fault they work such a useless company. Because I had made a complaint about past bills I was passed into to Sobia Begum of the Escalations Department, she seemed fine on the phone at first, she offered me £25 as a 'goodwill gesture' for my issues as long as I redrew the complaint. When I said I wouldn't redraw it just because they offered me a bribe, I explained that if they was to do a better job with their customers they wouldn't need to offer 'goodwill gestures' so I asked for the complaint to go higher than her and to keep the money offered. I recieved a bill for Mays usage (Junes bill) for £729.78, considering I'd left then in April and I'd paid what I'd assumed to be my final bill, so i phoned them yet again, finally got through after about an hour. Was put straight through to Escalations Department. Spoke to a gentlemen called Gordon (Head of Escalations) he informed me. Said how sorry he was with what I'd gone through and offered me £35 as a you got it 'goodwill gesture' for my issues. Even I said to him can you see on your system when I ceased being a UW customer, he said 'yes on Sunday 30th April'. I then asked him can you see if my readings for April where inputted into the system and if he could see the photos I'd sent and the written readings. 'Yes' I can see them. I then asked why I'd recieved a bill for Mays usage when I lefted them on the 30th April and for figures way over any usage I'd ever had. When I say way over, I mean 1988 unit of electric and 403 units of gas. In the entire time I'd been with them I hadn't used those amounts of units in the 8 months for both combined.. on average I used 100 to 150 units of electric and 30 to 40 units of gas per month. I worked away a lot. He looked at the Mays usage and said 'I'm baffled as your figures were imputed but it looks like someone has edited them after you had put them in on the app and after the written and photographic proof had been confirmed by UW'... he said he would investigate it straight away and would call me back within the week. That was 2 neatly 3 weeks ago and I've had no call. But I have had an email asking for the £729.78 to be paid immediately or risk having bad credit. Tried phoning them numerous times but no one answers. This company are a joke and should be shut down. If I was able to give minus star rating I would.
