This afternoon from 12:00 to 12:26 I visited the website silk-avia.com. on this site I booked a ticket for the date 05/12/2024. when I first searched, I chose 05/12/2024; when booking, the site showed me the date 06/12/2024, but I changed the date to 05/12/2024 and issued a ticket. After payment I received a letter with a ticket dated 06/12/2024. When contacting the airline, they want proof that I chose the date 05/12/2024. but I didn't find it in the browser history. can you help me with this
