They are using directtrack to track impressions, clicks and leads. They are not tracking potential customers correctly but clicks are shown in the report. After 12 hours of waiting, I sent an email to my affiliate manager, but I did not answer. I can not say that they are 100% scam, but something is wrong with them. I'm pretty sure I have more than 3 potential customers.
