[Resolved]  Flipkart — no refund received

I had bought a product indulekha with gift card balance. The gift card validity was till 30th june & i have placed the order before that. I received the product indulekha hair oil, but as it was duplicate product i have returned it. But i didnt receive the refund for it. Every time i call flipkart customer care agent says to me its already done but when i check gift cards balance on profile it shows 0.
Look into this. I have called 7-8 times & i get told that it'll be resolved in 2 days but not happening.
