Calcutta Electric Supply Corporation [CESC] — wrong meter reading informed with proof photo of current meter reading but yet no response

Address:

700040

My meter no. Is 3171329.
Last month's meter reading as taken on 19th feb 18 was 26373.
This month on 21st march was taken as per sms info. Though the meter reading sms didn't come.
The bill sms came two days back with huge bill amount. So i opened my duplicate bill on net and downloaded it. The meter reading was 26671 ie 298 units consumed which is absurd compared to my last few years consumption. No reason for this huge units in february as my home remains locked whole day from 1030 am to 6 pm.
So i took meter reading on 30th march and found it to be 26640. This proved that the personnel either didn't take reading or made an average. The photo of 30th reading attached as proof. I'll be waiting for your response. My bill due date is on 6th april 18.

Above is the complaint sent via mail to cesc three days back. No response has arrived. I am fearing this kind of wrong meter reading may happen again in future.
