Bata
Mismatching price tags

Hi..

i purchased a pair of bata shoe from its karol bagh showroom, delhi.

i bought it at Rs.1399/-. Later on i saw that the actual price is Rs.1199/- and a tag of the same amount was sticking both on the shoes & the shoe box. But the vendor superimposed the original tag by another tag and charged Rs.1399.

Please guide me about the course of action that can be taken against the vendor.
