Indraprastha Gas Limited [IGL] — complaint about unjustified charges for august 2018, as it is without taking reading for consumer no. [protected]

Address:

New Delhi, Delhi, 110027

Sir,
The amount due on July 2018 is Rs. 211/- and amount due in August is Rs.2070/-.
As the bill is without taking reading, the amount of Rs. 2070/- is incorrect and unjustified. Relevant screenshot is enclosed.
It is also submitted that no PNG is used from 5th July, onwards, as the house is locked . Hence the bill of Rs.2070/- is incorrect and unjustified.
Kindly send the correct and justified bill.
