I am cancel my order from amazon but i didnt get my refund credit in my account till now. Amzon already refunded my cash but still now didnt get in my account. They give a reference number and they told visit your branch with this reference number. I am already go to my branch today but they told to they can't track with this reference code. So please take a action about this same.
Thank you.
