Delhi Jal Board — sewer department

I made a complaint (Complaint no. 172) for blockage of sewer.
The complaint was attended after a weeks time but of no use. On inquiring, it was told to me that mr. Sagar, engineer, is looking for this. After getting in touch with him, he informed me that the complaint was attended within a day. But sorry to inform you that next day no one has attended the complaint. The complaint was attended on 07.02.2020 but the problem still exists. As 8th/9th february was holiday so i contacted mr. Sagar on 10th february, 2020 around 3.30 pm and he was very rude just like he is doing my personal work.

Mr. Sagar is a public servant and he has not giving me any favour but he is doing his duty nothing else.

You are requested to please look into the matter.
