[Resolved]  Amazon India — fake sellers on amazon india (refund not processed)

I had ordered a book fro amazon which was never delivered. I was informed that a refund has been initiated (On card). However i havent received the same.

The order with an amt of rs 2383.78 was placed on 19th march;
Item name: starting strength: basic barbell training, rippetoe, mark
Sold by: gourav agencies (Seller profile)

The amazon customer care has asked me to contact the sbi bank since they suggest its a bank problem whereas the bank executives (Be it customer care or branch executives) rudely ask me contact amazon for the same.
Also i had another point wherein the seller gourav agencies hasnt processed the refund for other customers as well (As per the customer reviews). How come amazon is allowing such business on their website (Ref the screenshot for reviews). Refer the screenshot of the order status that is so misleading (On the way, but it's running late). These points are a question on the credibility of so called big names like amazon.
Kindly look into the matter.
