Non delivery of i-ticket n non refund of the amount paid

I had booked an i-ticket with PNR No 2344671077 on Dec19

I did not receive the ticket at home through courier

I had availed another ticket for travelling on same day with payment of Rs 360 to the TT whose bill number is 417416

The gist is that I have paid twice amount for i-ticket and ticket booked by TT in train for the same PNR NO 2344671077

I have not been refunded the amount till now inspite of two requests
