The thing is, in order to make sure that you are the one who sent the link is not something viable, if your friend went to the website way before he clicked from you, but didn't register from google, register from you, that still doesn't work. So in this situation, I am sure that what happened was your friend clicked a link and went to bitkong and checked but didn't played or registered at all, after that you sent a link and he clicked on that link and registered from it and deposited and played but since he clicked on the first google search first way before, his cookies registered there, which is why I think it wouldn't work.
I am not sure if this is exactly what happened but this could be the issue you are having right now. Hopefully you will figure out what the situation was.
What i know is he clicked the link and registered . I think to register there you just need to put email and verify it. Then he deposited after that he appeared in my dashboard not his username but I. My dashboard it tells me someone registred under me. He played And waggered but no commission. So he juSt withraw.
If he clicked Google first why would my affiliate dashboard tell em someone registred under me.? But no commission ? It's the strange thing.
However I will never promote this site but good luck to anyone who does. But better they keep tracking.
And the site is dying anyway because of this poor marketing .
