The product was a damaged one, i choose the return and refund option for that.processing for the return was done on the 4th and Amazon's executive collect the product the on 5th.
My refund process started on that day, but for so long I have not received the fund in my account yet.
Then I registered a complaint with amazon and as part of that they gave me a refund reference number and with that I went to the sbi branch to get the statement and give a written complaint to dispute the charge. However, I have not received the refund yet. So I request you to take steps to get the refund as soon as possible using my refund reference number.
