Sir as i order a product from amazon and i have gift card of rs 3658 in it and i ordered a mixer juicer grinder worth rs 3668 as i have to pay 10 rs more to place the order i paid it from my fathers debit card of state bank after sometime i got a mail from amazon regarding that your account is locked verify your debit card last two digit and billing address so i send them the picture of debit card as well as billing detail at there email [protected]@amazon.in
after that i got mail that verify the card detail by visiting your branch and say them to send us a mail but as the bank manager told me that fax service not available at our branch he give me a written note on state bank pad to send them i send it to amazon after they didnot replied my mail as after somedays i received a mail that your acc related to mobile no [protected] and email [protected]@gmail.com is closed permanently and said you have done transaction without the authorization of card owner as my father well knows about the transaction sir i want to complain against them as you know 3568 rs is not a less amount for a middle class family i send you the screenshot of email they send me and the note that was written by bank manager of my sbi branch i m attaching it
