And, if i make payment using amazon link then 50 rs will be credited in my amazon pay balance as a cashback. But today is 22 december and still i am waiting for 50 rs cashback on each product. And, i already asked help for amazon associate through chat they are just escalating complaint but at the end result is nothing...
