Telangana Southern Power Distribution Company [TSSPDCL] — high current bill charged

Address:

Flat No 111, Santosh Plaza Apartments, Champapet Main Road , Santosh Nagar, Hyderabad, Andhra Pradesh, 50059

A high current bill is charged for us from last 2 months. We dont even have many lot of appliances in our home. Every month usually we get a bill around 700 to 1200. If we use an air conditioner it goes up to 2300 that too in mid summer.
But the bill we received this month is more than 1800 where we didnot use any ac. And even the last month bill was higher.

There might be an error in the meter reading as per my knowledge. I[censored] look at the meter reading from august to september both ps and pv number appears to be same.

I have attached photographs of bills from july
