Got a bill with wrong reading. We have taken a new connection in july2019 since then we haven't consumed much gas as we were out of town. So our meter reading comes to be around 2 now, however we have already received two times bill for 9 units and 40 units till october end. Nobody has come to take the meter reading in our house till today. They are putting there fake readings in the bill. Please correct the bill.
Below are the details:
