Vistara Airlines — refusal to check in

I had my flight to gau scheduled for 1:35 p. M on 22.07.2019. I reached the airport at 12:40 p. M and tried to self check in at the kiosk but was unable to print my ticket as the system had some error. I was told by the kiosk supervisor to check in at the counter but due to overbooking by the airline i was not allowed to check in even though i reported 45 mins prior to departure. I would like to have my money refunded as i was not allowed to check in even though i had reached on time at the counter.
