Redbus — Refunding of money after ticket issue failure

I have booked tickets for Trichy to Chennai with Finch bus and an amount of Rs 906 was deducted from my account which was paid using Gpay QR code However, the ticket was not issued. RedBus provided a transaction reference number[protected] and mentioned that the money would be returned within an hour but to no avail!
We tried reaching out via email and phone call but received no response till date. The transaction date is 13th of May.
My UPI ref no for deduction of amount of Rs906 is[protected]
