South Bengal State Transport Corporation [SBSTC] — Refund money for cancelled bus

My ticket was booked for 27th Aug in Asansol Digha bus 5.45 from asansol to digha. In the morning bus was showing in the app hence I booked my ticket online but in evening when I called asansol depot they said that the bus is not running on that day and the ticket are cancelled, money will be refunded automatically. But I didn't receive my money yet. Kindly refund my money. This has been twice that the bus stands cancelled and my money has not been refunded.
