Myntra.com — us polo assn shoes/fake/very bad quality

I got delivered these shoes order no.[protected]-4006901 from myntra on 31/08/17. I tried these shoes on 5/09/17 for the first time and the result was shocking they started cracking from their very first use. I have never thought that shoes like this would turn up like this.
I tried calling customer care many times but number provided on website does not connect it always says this no. Is wrong. I tried returning the shoes from their website by putting return request but their's delivery guys said your item is not approved for returning so it cant be taken back. I strongly feel that the shoes are fake us polo.
Shoes are having 3 month warranty for any manufacturing defect but i thinks its quality is really bad.
I want full refund of my money.
