I have a doubt in my mind that either Electric Meter is not working properly or someone is doing Electric theft from our meter as we are unable to check what exactly is happening.

So you are earnestly requested to take necessary steps to solve this problem as soon as possible. Your early cooperation will be highly appreciated.
