Getting online access to my account

I have two OVO accounts at different addresses.   Whenever I try to log in to view either of these accounts a message comes up saying, “We’re working on a new website for you.”   It has been saying that for weeks.  In the meantime, I am being asked to provide meter readings but I cannot because I can not do this online.   ‘Phoning OVO (when I eventually got to speak to a human) was useless: I was told to wait a few days and then I should be able to get access.   Like virtually every utility company it actively hates its customers
