Am I just over reacting?

So, I claimed a on the giveaway chat, and on the message there were said that the first person that claimed the cub could have it, so ofc I claimed in the chat because the cub was pretty cute and I'd like some new members for my pride, but as the time went on I didn't recive any cub as I was checking just out of curiosity I noticed that the SECOND claim got the cub :/ even if I was the first one that claimed, idk, I'm kinda mad, like I'm pretty open to Dms and if there were any problems I do rather that they contacted me even just for saying "sorry I don't feel like giving it to you" (pretty bad, but I do rather that, then what happened.) So I'm thinking about blocking them Idk. What do u think?
