I have requested my paypal authorization pin since 3 months ago. But they didn't send it. And then requested it for the second times 2 months ago. But none of them arrive in my address. Well, I have double check my address and it is the same address that I use for my affiliate check. Then I tried to contact them several times through email. But they didn't respon my email. That's weird. Do you have any experience with Clickxchange? Is it scam?
