Morestore — Discount not given by the store as per advertisement

Address:

122001

Today, i purchased vegetables, fruits, groceries from more mega store, sohna road, gurgaon. I also purchased nike shoes (One pair). As per today's advertisement provided in the leaflet by more, assured flat discount of 60% on nike and puma.
The pair i purchased was having original mrp of rs.4000, but at the time of checkout, i was given only 50% discount and not 60% as provided clearly in the advertisement leaflet released by more.
By such ways, the companies like more, tries to befool the consumers. How can they not provide the discount as declared?
It is earlnestly advised that the balance 10% discount be given to me which is my legitimate right else i will take the matter to further leagal recourse.
