Myntra - Myntra blocked my refund worth approxINR unethically and fraudulently

I am in need of some genuine help in dealing with Myntra. I am so tired and fed up of them. I have my account registered with email id "bi***.suc**ta@gmail.com". The items were an addidas shoe and * athena red color coats for women.
All three products have been kept on hold, saying quality check not passed. I am extremely amazed and disappointed to see this tactic from them. All products had the original packaging and price tags intact, yet they have given a very fake reason and blocked my refund and also “kept the products with them”.
MY QUESTION TO MYNTRA IS" WHEN YOUR EXECUTIVE OPENED EACH PRODUCT, VALIDATED THE PRICE TAG, AND QUALITY AT THE TIME OF PICK UP AND SAID EVERYTHING WAS FINE THEN WHAT MADE YOU BLOCK MY HARD EARNED MONEY UNETHICALLY???"
How unfair to keep all the original products themselves and also block my refund.
My complaint I work on very busy work schedule and also having to manage following up with them umpteen number of times. I request a speedy resolution and that my entire money be refunded. I am really frustrated that a national level company get resort to such fraudulent measures.numbers for these products are below, and I have been calling them with no resolution at all: *) IN******************** *) IN********************

Thank you
