As did I :
' So what happens when you SELL ME keys you actually do not have anymore? i'm just told i'll get keys when you have more? this is tantamount to fraud. You should NOT be selling stuff you do not have, now i'm out of pocket and have absolutely no idea WHEN or IF, i'm even going to get what I paid for. If this was some dodgy site like G2A I would probably expect it, but I didn't expect it here.'
And I got a reply:

Hi there,
Thanks for reaching out to Humble Bundle Support!
I'm sorry to hear that there have been some issues with your recent order.
The keys for this game are indeed temporarily exhausted. We receive Steam keys manually from the developers we're partnered with, and once we are able to acquire the keys we can update the download pages accordingly!
We hope to receive new keys this coming week, however we do not presently have an ETA from the developers. We would recommend checking back on your download page in the next several days.
Since we do not have a key presently, we would be more than happy to refund the order for you - just let me know if that is preferred!
Thank you,
-Twodee

For less than £5 total i'll wait, still naughty though imho.
