I understand how you feel, it's painful but don't give up, for them to distribute to some participants, that means it's not a scam project. Try to find out if there is a mix up some where. If not, just wait penitently you will receive. I did an airdrop campaign, some person's receive immediately it was over, I received mine after 3months. My mind was even off it, when I saw the coin, I was really surprised.
