United Colors Of Benetton — color of the shoe has become patchy

Address:

New Delhi, Delhi, 110049

Bought a pair of brown shoe from the benetton shop at the delhi airport shop (T1). A month later the shoe looks very very patchy with the colour just giving off at various places. I am attaching photos of the discoloured shoe. I do not expect such materials to be sold by such a reputed company. And i have been a customer of benetton for a very long time

Where do i send the shoe. Would you kindly replace them.
