Amazon India - Amazon malpractice to earn extra from rejected exchange order

On *th November **** placed an exchange order No.ORDER # ***-*******-******* for my old TV with a new TV. For this exchange Rs. **** was deducted. Additionally Rs. *** was taken as pick up charge against separate order No.# ***-*******-*******. Amazon delivery boy came with new TV and found my old TV unacceptable. Hence we had paid Rs. ****/- which was deducted for exchange. When we asked for Rs. *** refund he refused. Later I contacted Amazon customer support to get Rs. ***/- refund. But they told that since delivery boy has checked my old TV hence I have to pay this Rs. *** as their checking charge(refer screen shot of chat). How ridiculous, the delivery boy came to deliver new TV and he just seen the old TV and rejected. No separate visit or separate person came to check old TV. Still Amazon wants Rs. ***. Although it was written in order(attached) as pick up charge, now they say it is checking charge. Such a fraud company Amazon India has become to cheat the customer. I have taken exchange order from Flipkart, they also take Rs. *** as pick up charge. But this charge they keep in same order with the ordered item. But Amazon keeps it separate with separate order no to fraud the customer even it was not exchanges.
