Liberty Shoes — Selling defective, low quality shoes at premium prices

Address:

Ghaziabad, Uttar Pradesh

I bought a kids shoe of size 3 from liberty force 10 at a price of rs 650. The receipt provided clearly mentioned the shoe can be exchanged in case of manufacturing defect within 15 days of purchase.
My son wore the shoe to school and the sole came of on the very first day. When i took the shoe back to the retail shop (Within a week of purchase), the manager was rude and refused to exchange the pair upfront. After much persuasion he agreed to get it repaired. I am deeply disappointed as i was eligible for a replacement as per company. I would like to register a strong complaint and seek your feedback if i can go to the consumer court to redress my issue.
