Electricity Bill — too much of electric bill than usage

Address:

753010

I'm getting too much of my electric bill than the usage..in oct 2017 i got a bill of 973 and in november it's 1651 though the usage were same as in both months but the difference was around 700 more.. So i doubt if something is wrong with the electric meter or else someone is doing some unauthorized use of my electric.. I even have complained in the electric office here but there's no feedback.. So plz help..
