Ghaziabad Nagar Nigam — I'm complaining about sewage

I'm from Sanjay Nagar M block.
Sir/Ma'am I'm complaining about sewage blockage. In my house sewage water coming and spread foul odor. I clean my sewage (gutter) many times but after a few days sewage blockage. Sir/Ma'am actually the main problem is that main sewage (gutter) was full for this reason my sewage water was coming outside.
