Reebok India — refund denial

Address:	Pathanamthitta, Kerala, 689108
Website:	shop4reebok.com

I ordered a pair of shoes online via shop4reebok.com for Rs. 4499 on 8th July 2018. The product got delivered on 12th July. But I found that the shoes were not worth the money. It looked like cheap shoes. Without using it at all, I initiated a refund and the product was picked soon on 13th July. I followed up regarding refund for almost 3 weeks via phone since I wasn't getting reply for email. They told that it is yet to undergo quality test. Finally, on 4th August, when I called the customer care, they informed me that the product failed the quality test and it seemed like a replica. I am sure that I returned the same product which I got but they aren't agreeing. They are saying that they will dispatch those same shoes which they themselves agreed to be duplicate. I want my money back. Please help.
