If you find that a large big private company has cheated you with small amount like Rs.100/-, you will probably forget it and let it go. You will not go to lawyer or to file suit to recover Rs.100/- .
2) On the other hand the big company will have made millions of rupees by cheating millions of people by small amounts.
3) Since this is a Pvt company, there is nothing which government can do. It is a matter between you and the company.
4) The legal step which can be taken is to file a class action Representative Suit by any 4 persons who are cheated similarly.
5) In the suit, you can ask refund of your Rs.100/- with interest along with legal cost of litigation, but what is more, you can ask Court to direct The Big Company to refund Rs.100/- with interest to EVERYONE whom the company may have cheated similarly. This is great.
6) When such suit is filed in a Civil Court by any Four Persons, the Court directs that an advertisement about filing of suit be published in two national newspapers and two local newspapers so that other persons similarly cheated can also join in the suit.
7) This is called Class Action in other countries, here in our Civil Procedure Code, it is called Representative Suit.
