Respected sir,
Myself Satendra singh. Sir i have ordered to the website flipkart.com for eight number of books on different subjects.
All the eight books sent by the company in three times to me with full details and name of the books on the envelope of the
delivery. After one month company resent me a books among those of sent already while I did not give any order. There were no details about the book besides order number and total amount Rs. 385 on the envelope of the delivery. So, I receive it from the courier person and pay the amount but when i opened it I was surprised to see the book because I had already received this book. So I ask customer care to inform about the error. The customer care executive said that there was a system updater problem.
Sir I have no need this book. So please help me. Sir I have all the delivery records with me.
