Supersonic ads will scam you. They just say that you didn't use their offer even though you did.

I used another casino offer and they confirmed that I had used supersonic ads as referer and I submitted the chat log as proof together with all other proof they required (signup mail and payment) = rejected.

To be honest I think Nordeus should stop working with them. I don't think there are many people that actually get their tokens from those casino ads.
