There's not much we can do from our end so your best option is to send a ticket, send them an email, or get in touch with your affiliate manager. I've never heard of this network. I suggest sending your traffic to a more well-known network until you get this resolved.
Also did you check if they have a payment threshold? Most networks require you to make at least $50 sometimes $100 before they send out a payment.
Looks like they have different hold times for different offers, you can find more information here: https:// support .admitad. com/hc/en-us/articles/360019225718-After-the-user-performed-an-action-how-soon-will-I-get-paid-
