Snapdeal — complaint about refund money of product

I brought a shoes from Snapdeal at a cost of 1599. Shoes quality was not good. I return the shoes same day. After that I received a confirmation email from Snapdeal, that they received the shoes. After that day they never contacted me for refund. I called Customer care several time. Every time they said, I ll get the response within 24 hours. But never got call back from them. Finally I stopped calling them. Please return my money back, or allow me to purchase something and adjust the money. My order number is[protected].
