Scammed by cupid

Day 5,569, 05:17 Published in Brazil Brazil by Cupid Event Was a Scam

In short, I finished weekly challenge, gifted all my gifts and am still 540/600, not nearly as close to finish 3/3 challenge.
You could say i need to buy pack but its only 10 gifts, i would still need a lot.

So i spent so many resources and time during the event just to be scammed by bad luck?
How is that fair?
Or am i missing something??

Anyone else in the same situation?

Thanks!
