Bhopal Travels — No money Refunded

I have booked bus ticket from Bhopal to Rajnandgaon on 25th June 2023, the same evening I got a call from the bus service mentioning about the bus breakdown and so it has been cancelled, I chose to get the refund, the guy agreed. Today is 4th July 2023 I have not received any refund yet, it was not even updated in Paytm portal. When I called them back, the guy agreed that the bus as cancelled and I'll get refund but don't know when.
