Khadim's — Defective shoe

Address:

Hatibagan, Kolkata, West Bengal

I bought a pair of black belly shoe from Khadim's for Rs 499. The leather like material of the shoe started coming out after 3 to 4 days. It's been two weeks since I bought this defective shoe. The handle like design of the has come out. The full stitch has come out. It seems like 20 years old shoe. Very dissatisfied with their service. Is Rs 500 a matter of joke ?? How can they sell a defective product.
