CraftsVilla.com — About refund

I have bought 4 products at different time from the website of approx Rs.6000. When I returned the item I opted for bank account but the money was returned in craftsvilla wallet. I kept only one product of appropriate Rs. 3000 and rest were returned. My wallet was credited by amount of 3000 and after few days suddenly there is no option left of My Wallet in Craftsvilla app. I contacted customer care but yet not received any reply
