Fraud by House Owner / owner cheated - water bill - every month
We are staying as tenant in one house paying enough money for rent 12k .There is total 5 tenants + 1 Owner = 6 house in building. Every month sufficient water coming from kaveri around 70000 .If we divide the 70000/(30*6) = 400 per liter/house/day which is coming on calculation.
But owner taking extra 8 tanker changes which is 350 rs per tanker and it is coming around 600 rs to every house/month.owner having around 6-7 members in house and they consume more water than others .Owner excluding himself also.He don't have any proof for tankers and randomly he is taking too much amount from everyone.I told many times but he is not listening anything.
Please suggest what need to do ? What step we should take against him ?
