South Bengal State Transport Corporation [SBSTC] — Booking failure but amount is debited from account

Hi team,
My name is Debraj Sil. I travel to Karunamoyee, Kolkata, from Burdwan 2 to 3 days a week by SBSTC bus. Most of the time, I preferred online booking using the SBSTC booking app. My booking profile is registered with the name Debraj Sil, email [protected]@gmai.com, and phone number [protected].
Recently, a couple of bookings failed, but the amount was debited from my bank account. I share all the failed booking details below
