Mahanagar Gas Limited left debris on gate

On gate of my building for 2 months MGL left these debries. They r supposed to take permission before digging up from Traffic Police, then they r supposed to take permission from society/ land lord. In our case they never took any permission. Then they promised to level back trenches but never did so. The tenants supposed to be paying abt Rs 30/- pm but raping every inch of our property cared to do nothing inspite of being very rich. And finally as always happens I had to hire a person and level this area.
