So, I'm not sure but I think what's going on is that a scammer calls and asks the "victim" (in this case, Kitboga) to transfer funds into one of their Bitcoin wallet addresses. This can be done via a Bitcoin ATM which will then print out a receipt which the scammer asks the victim for a picture of (see [0]).
As Kitboga says, the scam normally has to end at this point because the scammer can easily verify whether the receipt is fake or not. So, instead, Kitboga and his team created a fake receipt that takes the scammer to the web and call center labyrinth, promising them they can redeem the Bitcoin at the end.
Third party Bitcoin management entities are kind of common now, I guess, so this doesn't raise any big red flags?
