Indian Railway Catering & Tourism Corporation [IRCTC] — tatkal waiting list ticket refund

I had booked a tatkal ticket on 1st nov for train on 2nd nov, the ticket was in (Tqwl) tatkal waiting list. According to the attachment i received from irctc themselves, the current status of my ticket registered with them is tqwl66, and when i ask for a refund for my ticket from irctc. The customer care tells me that the refund won't be processed and the ticket was confirmed. I am attaching a screenshot of my railway ticket status, i got from irctc on 25th of nov. I have already mailed them twice or thrice but it was of no help.
