GoAir — flight timing issue

Respected team
I am gurdev singh had booked a flight from hyderabad to delhi on 19/may/2018 and flight date is 29/june/2018. From the starting of the process i had opt the 10:20 am flight and when i had done all the payment then in confirmation chart, it is written that your flight timing is 5:35 am, this all is doing unfair with me, as i have face ample of errors in the go air website and one of the customer executive also told me that website is facing technical errors. While booking i have seen 2 errors and made the booking once again. I kindly request you that change my timings that i have made during the process (10:20am) and i am not be paying extra charges for this time changing as this is your fault not mine. Hope to hear from you soon.
Thank you
