Election Commission Of India (West Bengal) — No change of Address even after submission of required Document

Address:

Howrah, West Bengal

There are three VOter card where the above change need to be affected for 3 family member Debasish, Pampa and Anjali Mukherjee. I am from Bally Constituency (169). My Family has moved to a new flat under same constituency but diffent road (Monomohan Mukherjee Road to Panchanantala road (Part 14), both under same ward No 3) and accordingly I submitted requisite form and relevent documents last november and attended the hearing date as informed to us. However no body can provide us information why this is not done. I feel as per the right to Know the information Act, I would suggest Election Commission to let us know why this has not done?
