Gujarat State Road Transport Corporation [GSRTC] — refund of my ticket against booking and reservation time not honoured

Der concern,

I had a booking confirmation through gsrtc website from statue o[censored]nity (Navagam) to baroda central dep. Time 18:20.
Pnr number: g28712481
Ob reference no.: gs8777623
I have been waiting at the pickup point from 5:00pm till 07:15pm.
I am not able to track the bus or did not get any response from gsrtc customer service.
I had to board ac volvo bus at 7:15pm with a new ticket.
The conductor had suggested to cancel the earlier booking vide gsrtc portal, i had tried to cancel but it portal shows cancellation time is over (Screenshot attached).
With reference to the issue, i request the authority to cancel my booking and refund the amount.
