Tamil Nadu Electricity Board (TNEB) — tamilnadu electricity board (tneb) wrong / excess billing

I am raja from padur chennai, i am staying in pacifica aurun happtness towers. My eb service number [protected]. My regular bi-monthly usage will be around 250 units and will pay around inr 500. But in the period 17th may 2018 to 21 july 2014 the consumption meter reading raised from 2160 to 2640 and consumed 530 units and bill came for inr 1978. Which three times more have to pay. Even i dont have ac in my home. I doubt that meter reading noted is wrong. Please resolve this as soon as possible because payment due date is 5/01/2015.
