I wish I could give 0 stars here. I have had a months long battle with Eon where I was almost £500 in credit in September of last year to now being almost £1000 in debt despite making payments each month. I asked for a refund of the credit at the time and within days this had changed to over £500 in debt. There billing is wildly confusing. They charge you hundreds of pounds then refund the charge then make other charges of various amounts then then refund only some of them. So confusing. I will never choose Eon again. Please save yourself the hassle.
