Eon

BlueBelle - your experience sounds familiar from descriptions from friends who are with EON.

You have my sympathy BlueBelle, when you finally speak to a human tell them you want your experience escalated as a complaint. That usually gets someone whois understanding with cross customers and in my experience a rebate. Worth a try. In fairness I haven’t had your particular issue with incorrect phone numbers but have been locked out of my account for no apparent reason. We pay our bills by direct debit so little need to contact them.

As conergran says when you get through say you want to escalate it to the complaints dept. Tell them due to the stress and having to waste so much of your time trying to sort out their error with the wrong phone number and also not being able to log in/time on the phone you will be leaving. I did this with Eon (have now changed supplier) and got a £30 fair something or other payment off my bill. Eon for me were awful and now I hear they've done away with their dual fuel discount and the discount for paperless billing - a sneaky way to increase prices without putting prices up me thinks.
