It happen on many bounty, look like many of new project just want to get free advertising on signature campaign.
Irfan already asked the team but the team refuse to answear " when " with the " Busy " reason.
You have two possible outcomes here. You get paid or you dont get paid. Either outcome will not be escalate if you keep pressing on the matter.
I suppose you have already faced the frustration of having worked hard on a bounty and then not get paid. Get used to it because that is the reality of the situation and step out of the bubble.
Now I suggest you to look for other ways to keep yourself busy. If the team is legit and working you will get paid one fine morning and that will be a beautiful feeling for you after a couple of months because you kept yourself busy with other stuff and had forgotten about this bounty. Has happened with me once a time when I took part in a few. Stopped taking part in bounties from then on though.
Irfan is a good manager with a good track record. Let them handle the situation. Try to understand their situation too, having to keep a horde of hunters calm while trying to get information from the team who treat them like a slave.
