Consumer Redressal

I booked a I-ticket through IRCTC portal. I-ticket was not reached me. While asking IRCTC, they directed me to ask Overnite Courier. The courier, at first, informed me that the material reached the destination and provide a mobile no of recipient. When I approach that mobile no, i come to know that he is from mumbai and he did not receive any tickets. I informed that to the courier company. At last, the courier delivery man accepted his mistake that he misplaced the ticket and informed me to get duplicate ticket. He assured that the amount will be given by him. As I wanted to cancel the ticket, It was required original ticket. When I approach Courier company again through IRCTC, The Courier company confirmed to refund Rs.2910. However, the courier company is giving false commitment and not giving me refund.
