Myntra.com — Shoe replacement

Address: 115/234 Aggarwal Farm, Rim Tirth Marg, Mansarovar

I had ordered a pair of Red Tape Women shoe, with 1 year warranty. Myntra claims that MRP = Rs.6, 099, Discount = -Rs.4, 758, Coupon discount = Rs.190,
Total Paid = Rs. 1, 151.
Now it is torn in just 10-20 days after the day of purchase. I am seeking for the help from myntra for the same, they refused to give me refund or replacement for the same, the quality of the product is very poor, it might be a copy of the brand or myntra is fooling its customer, I am very disappointed with this e-commerce platform. While calling them they are giving me fake assurances that I will get call back from their escalation team, but I haven't get any sort of help from them. I am looking forward for the replacement of original quality product. I request to the person whoever is reading this, kindly help me out in this asap.
Thank You.
