Meanwhile they already had one readings, not taken but rather "estimated", from 1yr ago.
Fact is, the readings I took today is actually lower than their "estimated" from 1yr ago (btw "estimated" is a nice word, just what does it mean???), and their portal rejects my submission. It Say like "a later reading cannot be lower than an earlier one"
They dont give a telephone number, so I emailed them. We will see....
