UPDATE:

Sypoort staff member Eila who is the best support told me to context host provider of the event and told me to view the forum which led me to BC_Panda and so I mesaged them on telegram.

Panda gave me all the info I needed and has been very kind and helpful with fast respond. We both checked my UID to see if it was listed as winner but it was not. 

Doesn't make sense why to be shown message saying I won if I did not. Maybe error or glitch.

Panda said they contact event host and waiting on respond.
