Ghaziabad Nagar Nigam — Overflow of main sewer.

The main sewer of Sector 15 house number 239 to 249 has been overflowing for several days and the sewer water is flowing in the drains due to which the street is smelling very bad. I have complained several times by calling orally but till now this work is not done and it is continuously overflowing man sewer for two-three months. After about 10 days, it overflows again, please get it fixed as soon as possible.
