Flipkart — Replacement of the product is cancelled without the knowledge of the buyer

Address:	Chennai, Tamil Nadu, 600100
Website:	www.Flipkart.com

This is the order id: OD[protected] and the product is V-guard crystal plus voltage stabilizer. I have ordered this item in Flipkart on 1st April 2016 and bought it from the seller named ' Alpha Shopee' . It is delivered on 8th April 2016. The derlivered product is damaged very much. The plastic enclosure of the stabilizer is broken entirely. Hence I requested for a replacement of this product. The request was initiated on April 9th 2016 and the Replacement(return) ID is[protected]. It was mentioned that the delivery of the replacement product will be done within 19th April '16. So I waited till 19th April, and today while tracking the Replacement product I come to know I got cancelled without mentioning any reason. I adhered to the return policy, I requested the return/replacement the next day I received the damaged piece. Then

Why the return has been cancelled?

Why flipkart is not taking responisibility to replace the defect item?

Is that any of the fault from Customer side to receive such failure item?
