Delhi Jal Board - water bill and water quality

My K No. **********. I am fed up of Delhi Jal board because they send us the bill of ****/- for last * months. I don't know why because in my family there are only * members. We are not using water that much. In my same building rest of user gets only *-* hundred bills. I don't know why my reading is that much. I wanted to recheck my meter and correct the bill. Also from last *-* days, the quality of water is very poor water smell like hell. We can't use. It smells very bad. We want to resolve this problem too.
