I got message to from axis bank there is a coupon for Clayton watch cost 2499 can be claimed by paying only the shipping charges. So using that link https://flatworldrewards.com/ and ordered CLAYTON NOBLE SILVER METAL WATCH MALE paid the shipping charges (499 INR) on 31st May 2019 but the product is not yet delivered till now. Called the axis bank no proper response, saying it is a merchant issue. Called the flat world rewards, it is always switched off. Emailed but no response. Looks like this a scam/fraud. I'm doubt about axis bank credibility.
