Puma — Sole is falling apart from shoes

Address:

Durg, Chhattisgarh

I had bought a sport shoes of puma from flipkart on Wed, 15th Oct'14 and now the sole is falling apart from back of the shoes. Same case is there with the sole on other side also. Also the stitches opened up. The shoe costed me Rs.1899 and it has not survived even for a full year. Although my usage was not heavy nor i use to play wearing the shoes.
