Richard Evans’ complaint mirrors my experience.
 The green bars in the online Energy Usage chart do not mirror the “energy used” in my bill. Why the difference? There is no indication that the Energy Usage chart is supposed to be estimated, so they should be the same.
 Every month I have submited actual meter readings 4 days before cut off, yet every month I see estimated readings. It is not clear
(a) whether my bill is based on the actual or on the estimated readings
(b) why there are estimated readings, since I submitted my actual readings in good time.
I called and was told that the estimated readings would no longer appear if I submitted actual readings on the actual day, but in fact they continue to appear. I simply want my actual readings to appear. How to get this?
 I have been told by the online help that the emailed Bill is only estimated. This is very confusing. Please can you explain what numbers are derived from actual readings, which from estimated readings, and why there seem to be so many different readings?
I apparently have 4 different sets of readings -
my actual reading
your estimated reading
the reading in the emailed bill
the reading in the Energy Usage chart
Please tell me which are actual, which are estimates, and why all these different readings and estimates differ from each other.
 I find that the people on online chat are obviously incompetent and do not understand Bulb’s processes, but are apparently content to read from pre-scripted responses. It is not helpful when there is a genuine cause for confusion (see above), to get answers which only add to the confusion.
