Indian Railway Catering & Tourism Corporation [IRCTC] — refund about waiting list tickets

I booked tatkal ticket on 29-aug-2019 from secunderabad to rajahmundry for 2 passengers with pnr no. [protected]. Ticket status are tqwl 22 and tqwl 23 at the time of booking. The next day ticket got confirmed for 1 passenger and tqwl 1 for another passenger. Generally waiting list tickets got cancelled and refunded automatically. And also they are not allowing to passenger to travel. But now they are not refunding and says that i had to cancel manually waiting list ticket. They are not allowing passenger to travel. Why should i cancel to refund. They are not sending any instructions regarding this. Anyhow that ticket is not valid then they have to refund. Attaching ticket for reference.
