Myntra.com — account blocked and not accepting my return and refunding my money

I have been making purchases from myntra from so many years. During the eors sale i made my biggest purchase amounting to rs 1 lakh. And when i tried to return my products back which didn't fit me or meet the quality they blocked my account and on emailing them and calling them multiple times i get a reply that it cannot be undone and they won't take my returns any further because i have breached their online policies. I have always been their prepaid customer and i would like to know which online policy have i breached. Making a purchase of such large amount is a breach of policy.. I m seriously very pissed off and will take this to media and court if you don't take my return back and return me my money in my account.
