Myntra.com — Return product quality check failed

I had ordered a jeans ( high rise skinny fit Levi's black 721) on 20th december from mynthra.
It arrived early on 24th December. The jeans was of poor quality..I have previously also ordered Levi's jeans ..but this time quality was very bad and I got super skinny one(I ordered skinny fit)so I requested for return on that very day.Due to some misunderstanding it did not occur on 25th..but on 26th it was picked up successfully.Then after that I got a message telling my return request was" put on hold" as it "failed to pass the quality check"I called up the customer care..they told they will look into the problem..and I again got a message telling they are reshipping that product back to me.WHAT THE HELL IS THIS????? I have also purchased from other e commercial sites and have never faced a situation like this. Since the quality was bad and I got a defective product..that's why I have placed for return request on that day itself.why r u doing this to people..I want my refund..you have sent a defective product and now tells that we have made it defective...This will be my last purchase with mynthra..very disappointing!!
