How to get cancelled Nol World Tickets (Stray Kids 6th fanmeeting)

I was wondering if anyone knew any tips or tricks on how to get cancelled nol world tickets. I did as much research as I could but I couldn't find much. I was able to get a ticket during fanclub presale but it timed out so I got the ticket and then they immediately refunded me :( I tried again for general sale and the obstructed seats one today and they were completely gone when I finally got in. I am devastated as I already bought my flight and hotel. Please let me know if there are any tips you know, and thank you in advance!
