BlueSnap marketplace - will my vendor get paid?

I started selling through the marketplace in BlueSnap - I sell subscriptions, and I created vendor accounts in BlueSnap for my promoters who sell for me.

I basically created the vendor accounts with just the promoter's name, email and country:

{ 
    "email": "mark.cooper@gmail.com", 
    "country": "US",
    "firstName": "Mark",
    "lastName": "Cooper"

}

I was told that's it - and that I can sell with those vendor accounts. I sold for a few weeks and I got my share of the payment for the subscriptions - but my vendors didn't.

I want to sort it out, do you have any idea why this happened, how can I fix it for the future – and what I can do to get them paid for the past sales?
