Amazon India — Gift card return

Address:

New Delhi, Delhi

I recently got a gift card from my company to buy Arrorw product and get rs 1000/- flat off on the product. I ordered 1 shirt that cost me rs 1299/- and I applied the code and got 1000 off, I paid rs 299 via card. The shirt that was shown in the picture was too great and was looking very cool but when I received the item it was very dull.
Then I thought to replace the shirt with another item but I didn't got an option for replacement, it simply state to return the shirt. I returned it but didn't got my gift card back to my account. I spoke with many representative about it but all said they can't give that. So if I got that gift card from my company and then why can I get my card back..?? I also said to send me the shirt back to me I'll not wear it but keep it with me and then also they said they will not send the product back. I mean I only shop online and that too from Amazon or Myntra only but now I think it's high time to not to shop from Amazon anymore.
Just requesting to refund back the gift card or send my shirt back.
I thought Amazon is a very good site and I used to recommend to other's as well but I think that's a very big mistake and will not sugget to anyone nor will say to anyone to shop from Amazon.
