Not sure where to post this but I completed a task for monsterwod and never received my gems. The task was reach power level 50k for a game and i completed it but when I returned back to monster legends I never received the gems. Normally I wouldn't be upset about this but this is 1.3k gems I literally got cheated out of. I messaged the other games customer support and they said They are unable to see any third-party offers and when I messaged customer support for monster legends they never got back to me.How can I email them about this issue or where can I go to report it and get the 1.3k gems I should have received.
I would post the screenshot but it won't let me

See HERE on how to report the issue to the third party servicer.
