Flipkart — PRAKASHASUNDHU, a book written by Suvarnna Nalappat

I had ordered a Malayalam book named "Prakashasindhu" Written by Smt.Suvarnna Nalappat. But another book was delivered. I made a request for replacement which was accepted. But on 23rd August this request was cancelled without any replacement. Then I contacted the customer care and again a replacement order was made and the book was supposed to be delivered on[protected]. But they again cancelled the request without replacing the book. This is my grievance. I want a replacement of the book or refund of the amount. Please do the needful.
