I started using TraffMagic in 2017. It was great then, and it was okay up until 2018. Something must've changed because I no longer receive the traffic I pay for and they always claim they sent it. I have Google Analytics that shows everything. I've sent screenshots to them and they continue to state that the traffic had been sent.
I'm just waiting on my refund from my last failed campaign with them and heading to another provider. Proof below. Ordered 5K traffic in August for a post... you can see for yourself what I received from TraffMagic.
