I also earn $612 from them from april 10 to 21, and now i was wondering, that i saw a payment report in my account but i didn't receive any payouts from my paypal. i don't know if they send the money through check or paypal but i choose there to be paid through paypal not check.
Maybe you should contact them directly, this involves your account, so we won't really know what's going on with it or why your report says one thing, etc.
