Allahabad Nagar Nigam — Illegal encroachment

Address:

Mahewa

Hi
I request Nagar Nigam Allahabad to look into a matter in Mahewa, where their people have not left the road even for small vehicles to pass by, where there is a problem for the ambulance and other people. it has become a 6 ft narrow road now and there are some who will park the car on the road and use it as their personal property even,
So please someone here can help me out, or how can I complain and the issue can be resolved
