Anybody else have this problem?

Your statement will be billed at midnight on the day your statement is due. So if you send a reading before that day then it shows on the statement but will also be estimated upto the day of the statement. The DD wont change and any over under reading gets corrected when you send the next reading.
To prevent this from happening send the reading in on your billing date and it wont get estimated upwards.
