After that i am still following them to refund my money, , ,
Then i got a mail from amazon customer care that the refund is initiated & it will be reflected in your account by 8.4.2015, but today ie 9.4.2015 i checked my account there has no fund hasbeen received from amazon, then i write back to amazon for the same.
Now they told me that the cheque has been courier to u by blue dart courier number [protected], in blue dart site the courier number is does not exist
