Sastiticket.com — Ticket not issued and money not refunded

I had booked tickets on sastiticket.com on February 14, 2021 (reference number PRL0BQ0L77K).

After the ticket was booked and payment was made, got message stating that the ticket are pending issuance from airline and hence the money shall be refunded. However to date the money is yet to be refunded and there is no response from their customer service team on the follow up mails i have sent.
