Mahanagar Gas — excessive bill amount

I am quite shocked to receive the gas bill amounting rs. 2093/- against electricity consumption, for the last month at my residence. It is just not possible for me to have used so much consumption in the last month, more so because i was out of station with my family for twenty days and the house was locked. There seems a mistake in noting down the initial reading of the last month
Please rectify this mistake so that i can pay the actual amount.
