Tskhadi — Not getting refund

I ordered a saree from this site and found it was not good quality product so returned the same on 18th Dec. Since then I am regularly calling them, massaging on whatsapp and even sending them emails. They are not responding to my emails and on phone they assure me refund within next 3/4 working days, which is not happening. This site looks fake as I come across lot of similar complaints of this company TSKhadi
