PayTM - Declining to refund

I booked a bus ticket from PayTM with Order No. ********** on **th Aug ****.
I even raised query on PayTM with Query Ref no. *********

I contacted PayTM help center on ** Aug **** and wrote something like this.
My bus got cancelled midway just one hour after I boarded the bus. Bus depot counter and bus conductor told me to contact paytm for refund. They told that bus is stopped midway due to road blockage because of rain so bus isn't updated as cancelled online.

Then they replied me on same day, "Greetings from Paytm!
Thank you for contacting us and
apologies for the inconvenience caused.
We would like to inform you that as per
your request raised against the Order
********** our team is working to get
a confirmation from the operator.
We request you to please give us **
working days to work on the case and
revert with a positive resolution. We seek
your understanding and patience in this
matter

booking order, we shall revert within **
hrs.

And then again on ** Aug **** they replied,
"Greetings from Paytm!

apologies for the inconvenience caused

Then forget ** hours, they didn't reply till ** Aug ****.

Then on ** Aug **** I contacted them wrote, "Hi, How much more time you need, You said that give us ** days and It has already been ** days without any resolution. I know very well that Bus and PayTM help center are open **×* then why so much delay?"
To which they replied, "Sorry to hear that. We are looking into this on priority."

And then after several hours on ** Aug **** they replied this, "Your request for full refund on journey
date ****-**-** has been declined by
Bus Operator.

We regret the inconvenience caused.

determined solely by bus operators.A

And then I contacted Bus Operator and they're asking me for PNR Number and OB Number. I have PNR Number on my ticket but there's no OB Number written on ticket.

So I again wrote them this,"I want OB Number,
give me that. I'll directly contact Bus Operator
for the issue. If you won't give me the OB
Number I'll file a case in consumer court,
you can't just fool and harass your paytm
users. Mail me every detail about this
booking including OB Number."

To which they gave their robotic reply," Your request for full refund on journey
date ****-**-** has been declined by
Bus Operator.

We regret the inconvenience caused.

Then I sent them this, " You wrote that "You may reach Bus Operator for
further clarification." I asked them for re
fund and they're requesting for OB Number
which I don't know, but you do. Send me the
OB Number, I'll no longer contact you."

After that I haven't got any response from PayTM till now.
