Amazon India — amazing customers team fooling customers

I had ordered a trolley bag from amazon. Since they gave an extra 10% cash back if we pay by pay balance, i recharged my amazon pay balance and used it. Then i didn't like the bag and decided to give it back. I wanted to order another. Before placing the second order i asked the customer service team whether they can give the refund in my bank and not as pay balance. The girl name bhuvaneshwari said that the refund will be given in pay balance but later on she will transfer it to my bank. I asked her twice if she is sure she can do it, she said yes not to worry. But the very next day the other customer service guy said it is not possible and they cannot make a refund to my bank account. When i said they had promised he said he can't do anything. The girl made a false promise
