Dakshin Haryana Bijli Vitran Nigam — Incorrect Billing

Meter readers are not taking correct unit reading. Because of that readings get accumulated and than a consolidate electricity bill is given to consumers. This bill is calculated on single billing cycle. But units are of previous months. It is resulting in calculation of bill on higher charge slabs.
I have approached local electricity office on several times but they are not listening. I am facing this issue for last 1.5 years and paid excessive bill.
Pls correct my bill as per charges slab of electricity.
Thank you
