Absolute shower of muck!
Never experienced such poor service and disregard for customers in my life. At the time of joining Utilita, I did so as I worked for Utilita and we had a staff discount plan. Thought id take advantage of it, but a massive mistake that’s caused problem after problem. I was a member of staff and have experienced ridiculous service, so I genuinely feel sorry for a regular customer of Utilita.
Firstly when switchover date happened, I was set up on an incorrect tarrif which left us without off peak hot water and heating, the tariff was incorrect and I wasn’t on a staff discount plan. Took several hours on the phone to try and rectify, managed to get the off peak sorted, but tarrif was still incorrect.
Secondly, after utilita took over, it caused the meter to some how become faulty, and they well and truely messed up my meter reads. Phone call after phone call, I tried to explain my meter is faulty and the reads you have are incorrect. Tried to get it resolved and have a meter replacement, but probably easier trying to get blood out of a stone. I’ve put in a complaint and it’s now somehow disappeared from their system. After a month of no resolution and simply becoming so stressful, i moved away from Utilita and went with another supplier. The new supplier came and changed the meter within the first few days, and I finally have correct readings. Since then, the ve had incorrect bills from utilita and demands for payments. The icing on the cake is they have sent me a bill for £1490 during the 7 week period I was with them!! They believe I have used 1963kwh during the day and a massive 8450kwh on my night usage in 7 weeks! Absolutely crazy and they refuse to listen and rectify their mistakes. I’ve even paid them £300 for the time I was with them, and if anything, I should be due money!. Received the bill today, and to add insult to injury, I’ve a £30 late payment fee added. I’ve honestly spent so much time with this shambles of a company, passed from pillar to post, put official complaints in and told things would be sorted. Yet still, they do not care, and will chase you for money you don’t owe. I honestly would recommend that no one touch them with a barge pole, and feel sorry for anyone else having to go through what I’m going through with them.
