Any queries I have, and I’ve had several, via email, text or WhatsApp aren’t answered and I have to go through the same rubbish every time - waiting 5 or 6 days or longer and then the conversation is ended without any satisfactory conclusion or even the chance for me to reply..even complaints are dealt with badly. The have probably the worst customer service I have ever experienced, no one taking proper ownership and no one giving a damn as they know we’re all stuck with them for the foreseeable future.. I am currently, almost, £900 in credit, just had a bill, have used just over £1600 energy in the past 12 months but pay nearly £300 a month as my ‘estimated yearly usage’ is just under £3600..£2000 more than I’ve actually used and they have data for..and there’s no one to find out why they’re bleeding me dry..utterly disgusting treatment.
