Humble didn't tell me that, I am sorry.
Just googled it and apparently only countries belonging to North America, Europe, Asia, Middle East, Africa or Oceania can redeem them (https://www.steamgifts.com/discussion/r5kVH/humble-bundle-payday-2-the-ultimate-score-bundle-return-of-the-ultimate-score-bundle).
If you have a friend in one of those countries feel free to send it to them, or I can reroll it so someone else can have it. Your call.
Again sorry that the key didn't work.
If you have another idea feel free to tell me.
