How come i didn't receive the payments from my form? 

I saw them in the 'Uncompleted payments" And clicked complete Submission on them, but they didn't come through into the paypal yet? 

Marking it as complete won't process payments. Check this guide to learn about why there are incomplete payments. http://www.jotform.com/help/135-How-to-View-Pending-Submissions?

We also have Paypal Incomplete Payments FAQ. Check it here http://www.jotform.com/help/272-Paypal-Incomplete-Payments-FAQ. You'll find there the guide on how to complete paid submissions.
