Bruhat Bengaluru Mahanagara Palike [BBMP] — Open Drainage and no way out of the house

Address:

1st cross, PF layout, Vijayanagar

We are the residents of the 1st cross, PF layout, Vijayanagar area.
We are fed up with the work that is being done in front of our house by BBMP contractors. it is been more than 3 weeks since they opened all the drainage in front of our house. They dint even leave the passage from where we enter/exit from our house gate. The workers are not even coming from past one week.
We are using a plastic bridge kind of thing to pass from our gate to road. There are senior citizens in the house as well. For their safety we have told them not to come out of the house. The other worst thing is the drainage stinks as they have left all the drainage water.
We the residents of the PF layout are really frustrated with this. Please take an action on this before our frustration level exceeds a limit.
