Amazon India — cash back for cancellation of order

Address:

Hyderabad, Telangana, 500073

I have ordered samsung m30s on 4th of october, 2019 i supposed to get it on 5 th but till 10th i am not able to track the delivery and no response from the customer service. On 10th they told me that please cancel the order and go for new order we will provide the additional benefit form our side due its our mistake just cal after booking new phone and tell me the canceled order number, we will provide the cashback. But once i ordered the phone and called to customer care they are saying that our customer service provider said a wrong information to you no cash back is possible. This is how there are cheating the customers.
