Delhi Jal Board — Wrong bill, giving more amount than our consumption

Address:

New Delhi, Delhi

Sir,
our k No is [protected] and from past few months we are getting too much amount of water bill.
We had submitted our bill when it came of ₹2000+(which is also not the right amount). But last month you had giving the bill of ₹6000+
which is absolutely wrong.The bill is generated on average basis.And it is also written on the bill that meter is reversed but in actual it is working properly.
Kindly look into our problem and resolve it as soon as possible.
