0 Stars. I hate Eon. I don't know how you could live with yourself if you worked here. I have written evidence of every claim. They harassed me about smart meters for years despite being notified multiple times that property is ineligible. Lied continously about removing me from mailing lists. Communication is APPALLING. If they reply to emails at all which is about 50/50 it can take weeks, and even then they will have totally ignored AT LEAST 75% of the content of whatever you said. They REFUSE to answer questions or provide explanations for actions taken. I emailed the CEO over 2 months ago and have had no response, so they're consistent (/ly terrible) at every level. They told me my meter was faulty then refused to investigate it for over a year (changed supplier) despite legal obligation to investigate. They sent engineers out for the wrong kind of appointment TWICE and offer lower compensation than the value of the work I had to miss for no reason. Their staff are really rude and ignorant, basically told me I was lying about claims I had written proof of, always ignoring most of my questions or requests. They illegally shared my personal data with a third party and have yet to acknowledge this severe error. They passed my account to a debt-collecting agency after stating IN WRITING that they wouldn't do that. Then after I got the debt letter they told me it wasn't genuine (IT WAS) and to throw it away, which would have resulted in a court summons if I had followed their instructions, so lied to me for a month about how my personal data was being shared. It took me ringing and emailing every day for over 2 months (over 22 hours spent trying to fix THEIR mistake) for them to reclaim my account from the debt-collectors, and for all that they offered me £30 and refused to even guarantee that it wouldn't happen again. Since the ombudsman is a useless, impotent organisation that offers 0 oversight of the energy companies (they aren't empowered to punish energy companies, therefore have 0 leverage to prompt behavioral change or adherence to rules by energy suppliers and can't in any way make the suppliers treat customers fairly and transgressions by supplier results in 0 tangible repercussions), I'm thinking this will be going to court.
