Delhi Jal Board — excess bill with less water supply

Hello sir/madam,
My Consumer Kno. [protected].
I live in G- block, Street No. 20, Karawal Nagar, Delhi - 110094.
Here is the biggest problem of Drinking Water Supply. Water is supplied for 2 or 3 days in a week for only 1 to 2 hours in morning before 7am. The supplied water quality is also very bad and non drinkable.
Due to this we have to pay for the water cane for drinking.
Also water bill is generated without any meter reading.
When water did not supplied then how to generated bill.
Please check and rectify my bill and supply the water properly.
