Was your recent visit to an expensive restaurant a disaster ? You found a dead rat near your seat ? Or may be purchased something from a store that doesn't work after you reached home ? You are now angry and want to go to every forum and yell out against the seller. I know, I can understand your frustration!!. You may always rush to the usual channels like facebook or twitter, but apart from writing negative reviews on social media, the right thing to do is to raise a consumer complaint.
Unfortunately, google points to so many privately owned complaint boards, that people are often confused with their effectiveness. After doing some online research and checking for a government owned solution, I landed on this site. Obviously, I haven't used this service so far. So let me know if it is useful.
Mentioned above is the website for Department of Consumer Affairs
Ministry of Consumer Affairs, Food & Public Distribution, Government of India
How do we register a complaint ?
Consumers can lodge their grievance by calling the toll free number 1800-11-4000 or 14404 and talking to an agent. Alternatively, they can register once in the portal and lodge their grievance attaching necessary documents.
For every grievance, a unique docket number is generated and are sent to the concerned. Action status is updated on a real time basis.
Let me know how your experience with them was.
