Tamil Nadu Electricity Board [TNEB] — Reading not taken-door locked-because of height of the meter

As per the last bill, it was mentioned as door locked.but because of height of the meter installed, they are mentioning as door locked.if anyone available/shop is open they are asking us to tell the reading after putting chair.but if the shop was closed, they are doing the same.
meter is also in normal height and there is no possibility of lower height installation due to children's may touch it and it is in the roadside too.
Visited EB office and asked to update the reading based on photo of the meter, they have informed not possible as per your wish, pay the same amount.
If i will pay then the next bill also too high, and this time cost will not be a useful one, like there will be no reduction.
