Amazon India — About not getting refund

In my order status it is showing product is delivered on 4 th June but product is not delivered to me. Regarding this I tried to complaint many times at Amazon customer care service. But every time they give different reasons. They were telling that they are contacting seller, they said that it will refund on 21 June. I called on 21 June then again they said you have to wait more and your money is safe. They are highly uncertain about my order. I want refund of my order. I want real solutions and not fake Reasons. Coustmer support team is very worst
