I had bought a pair of jeans from amazon, since i didnot like it, i returned it and has asked for refund on 19th may,
I have not received the amount yet.
Bank says that they are not responsible for the same and amazon says that they have issued the refunded amount.
I want you to kindly look at this issue and resolve my problem as soon as possible.
