lol exact same thing happened to me with Europeans. Ran an offer but was seemed to good to be true in terms of ROI. I hit them up said how’s it looking. They said looking great scale it up! Scaled to about 60k. They messaged me. “Looks like there’s a tracking issue”. They refused to pay me out the full amount, so lost a shit load on adspend. And said “we can do a compensation deal, we will give you more $ per conversion to make back your loss”.
Total jokers.
