Amazon India — issue with product delivery and mails

With a certain order i placed first i got mail seller is not able to deliver, later person to receive is not available. Than i went to amazon app to cancel order, there was no option for cancel so i placed refund request. On the day when return (As not delivered till now so return from mid place or seller only) should have been initiated i got mail order is delivered. Customer care are not able to see those mails, means customer care of no help only job to check mail and tell you. My money is blocked. Waiting to get that back
