Amazon India — gift coupon frauds in amazon

Hi

I bought a gift coupon from amazon for the value of rs.1500 (500 rs of max and 1000 rs of big bazaar.) when try to check the redeem processing, i got the link of the support site of both these merchandise. When i checked with them they told that the pin is reset and i have to contact amazon. I contacted amazon and gave the details. They told will revert back in 24 hours. But no reply i generated a new pin by resending the voucher from my app. Now when i try to redeem max fashion points to amazon and when i contact amazon they point on max fashion. There is no reply from big bazaar. I am daily contacting amazon but daily they send a link to submit all the details but no resolution from amazon, max fashion and big bazaar. Now my 1500 is in soup. I have already spent around rs 300 in visiting both these shops. Amazon had did the same fraud when the purchased a gift coupon for rs 5000 last december. I contacted the customer care. The total call duration was 42 mins, i was kept on hold for 16 mins and then my call was disconnected. Attaching screenshot
