Indian Railway — Incorrect Ticket issues

Website:

www.irctc.co.in

Hi I booked a ticket on BBS to HWH in train number - 12838. Ideally it should not show me the availability in Tatkal before 10 am. But it allowed me to book the ticket. When I received the ticket I got the confirmation on Falaknama - train number - 12704. I called the help desk on the issue. They are saying that I have booked for Falaknama and they can't refund any as per Tatkal policy. This is not correct and I should get the refund. PNR number - [protected]
