Andhra Pradesh State Road Transport Corporation [Apsrtc] — Refund charges were deducted for a failure transaction

Hi this is kiran,
I have booked a round ticket with reference no: [protected] in apsrtc online Booking.

Due to transaction failure during the online ticket reservation at apsrtc,
they have deducted Rs.54/- as gate way charges and refunded the balance amount. When the ticket is not generated how they will deduct
Rs.54/- as gate way charges.?

such a worst and disgusting services giving to customers. how we can trust you in booking tickets through their online portal. please take any actions with this issue. payment failure is not our fault then how can they take charges on deducted amount.
