Hi Team,

I booked a bus for shirdi trip for March 18th but due to vehicle issues the trip got cancelled by SRS.later i got the refund amount but there is difference in my paid and received amount.

Bus Ticket numbers
PNR 35913886

PNR 35913910

The amount debited for the ticket 35913886 is Rs.4788 i got a refund of Rs.4560
The amount debited for the ticket 35913910 is Rs.1596 i got a refund of Rs.1520

Could you please let me know why there is a difference in refund amount as I booked the bus through SRS portal only.
Please treat this as priority and refund my full amount back ASAP. It's been frustrating talking to everyone and it's been over a week for now and there is no response from them until now.
I'm attaching the refund and paid amount screenshot as well
