Omio complaint: Refund 470 euros : Plane ticket

First of all, I am not happy with the service that Omio has provided to me. I booked a flight from Malpensa to Belgrade for the 30th of March, 2024 through your app. I received an email ing that the payment was successful with the ation code HVGGBY. I believed this code was my reference for manual booking.

The day before my flight, I called Air Serbia to my flight and ticket details. They informed me that they could not find my booking and that it was just a reservation set to expire at midnight. They advised me to contact my agency. This ed me to call Omio on the 29th of March, 2024, around 22:00, and I spoke to your colleague, Jorge. I expressed my concerns and frustrations regarding the information from Air Serbia.

Jorge checked the system on his end, assured me that everything was in order, and advised me to do a manual check-in since I couldn’t check-in online due to booking through the app. He also recommended arriving two hours early for the flight to avoid any issues. My flight was scheduled for today, the 30th of March, 2024, at 9:30.

I arrived at the airport at 7:15 to ensure I was on time. However, during the manual check-in process, the agent informed me that they couldn’t find my booking and that my ticket had expired at midnight. It was determined that the issue was related to the booking agency. Air Serbia couldn’t assist me, and I missed my flight. I had to purchase another ticket, resulting in a stressful morning due to the services provided by Omio. I request a refund for this inconvenience.

Omio is refusing to give me a refund , when I have proof that they didn’t send me a ticket .
