Not sure how many of you already use them, maybe you do and don't have any problems. But from what I've experienced with them, their support is terrible. Over a month ago their postback script stopped working on one of my main earning sites. After lots of testing and debugging it turned out the problem was with Cpalead sending blank variables in the postback. After weeks of emailing, messaging them and calling them, support have done absolutely NOTHING to fix the problem, in the meantime I am having major issues with the site since the postback function isn';t working, i'm wasting hours of my time manually inputting entries that should all be automated. Fuck Cpalead, bunch of unprofessional cowboys, avoid them at all costs.
