Punjab State Power Corporation [PSPCL] — Daily at nights there is no power supply

Address: 1432/1, Urban Vihar, Jawaddi. Ludhiana

I have daily registered complaint on 1912, I received complaint no through msg but further it never assigned to any one, from last three nights power shuts off in evening and come back next morning.
No one is even caring about lodged complaints, who is responsible for this.
How can we work at our workplaces after awakening of whole nights due to poor services of pspcl. It's very shameful thing in such a big city like a metropolitan, but we are still living of a rural undeveloped area because of this power unavailability..
