I would mark this as 0 stars if I could for their absolutely shocking catalogue of errors. Utilita took over our account in Jan 2019 and we left them in Nov 2019. The bills we have are a complete mess - a mixture of customer and estimated readings on the same bill (how? When you submit readings you have to do it for both rates?!), incorrect recording of Direct Debits taken; very confusing pricing information. Then discovered they were still taking a monthly DD 6 months after we had left. They paid some but not all of this back in April 2020. Then in July 2020 our current supplier (Bulb) put our DD up massively. Turned out that months AFTER we had stopped being a Utilita customer, Utilita had 'disputed' our closing readings (which had months before been accepted) and unbeknown to us, submitted new, completely FALSE readings to Bulb, making it look as though the original readings were much lower and therefore we needed to pay for thousand of units....which we had already paid for while with Utilita. It has taken me weeks to sort out and recalculate where we should be and what Utilita owe us - several hundred pounds. I submitted my comprehensive complaints letter to them on 16/09/2021. I had to chase twice before receiving a phone call on 30/09/2021. In that call I had to go over much of the complaint already detailed in the letter - it was as though the person had not read the letter AND then follow up sending more info including resending things from the letter to convince Utilita with clear evidence that they are clearly in the wrong. The customer service rep said he would call me back at 10am the following day - 01/10/2021 - once he had investigated further (having tried to fob me off that the changed meter readings were correct when they are not - I have a photo from 01/11/2019 showing we had already used far in excess of what they are trying to say we had used on 13/11/2019 at the end of our contract). To date (it is now 19/10/2021) and I am still waiting for that call. I have chased 5 times and the only thing I have had is an automated text which can't be replied to asking for the information I have already sent. It is beyond a joke how poorly this has been handled at every conceivable step of the way and I find it very hard to see that this is not just a catalogue of errors but instead fraudulent & negligent behaviour on behalf of Utilita. Had I not spent countless hours of my own time on this - for which I do expect to be properly reimbursed - Utilita would be keeping hundreds of pounds of my money AND caused us to overpay for electricity already covered with them to our current supplier. As I am getting NOTHING back from Utilita despite the seriousness of the complaints levelled, I will be contacting the Ombudsman, Which, MSE and anywhere else I can expose this shocking behaviour. The complaint ref should anyone at Utilita actually deign to look at this is 159020249. I won't be holding my breath though....
