Refund — Refund against cancellation of bus tickets

I took three (3) red bus tickets fro travelling from Guwahati to Dibrugarh on 26th March, 2022 at 6.30 PM. But for some unavoidable reasons i have to cancelled the tickets. Immediately after the cancellation i got one msg that Rs 997 has been refunded after deducting Rs 780 as cancellation charge. But till this moment i am yet to get the refund money into my bank account. I have made the payment through my debit card only. As per the refund msg sent to me reflects that the money has been credited to my card but it is yet to happpen. Please do the needful at the earliest possible. Thanking you.
