I have previously had nothing but a good experience with Edf. Received an email a few days ago to say the account management system has been upgraded 'to make account management easier' - I have not been able to log in since!! I keep getting a 'network error' message. I used the messaging system to ask for help - 24 hours later they sent me a password reset link. Reset the password but still can't get logged in. I am back to square one - have had to message and email again and now have to wait for a reply to most likely go through the whole process again. So frustrating when the old system with my old account number worked perfectly. I am so frustrated with the whole thing I am considering changing suppliers.
