[Resolved]  Flipkart.com — Wrong delivery, product returned but didn't get money back.

Website: www.flipkart.com

This complain is of Flipkart.com which is online shopping site.I had ordered a book 'Nerds" .The language of book mentioned on site was English but delivered book was in other language, I called them and told about this wrong delivery, they said return the book and correct book will be delivered .
I again confirmed that whether they have English , they said "yes", then they assured me that they will deliver right book but again second time they delivered wrong book.This time I asked them to return money in the form of check ,but it's been 3 months I didn't get any money.Whenever I call them they say give me 2-3 working day and then nothing happens.
This is really frustrating and bad experience .
