I have purchased NCERT 10th cl book set (10 Books) from flipcart. However I rec'd only one math text book through courier. I have already paid Rs 925 on this product.
I lodged refund of money through online. But refund rejected. What can I do now. I lossed my money as well as precious time due to this flipcart purchase.
