http://www.direct-link-ads.com/ I have a balance of about USD100 in my account. I did a withdrawal, waited for 10 days and still no money from them to my paypal account. Emailed the address listed at Contact page and it says "The account or domain may not exist, they may be blacklisted, or missing the proper dns entries." Crap..
That's fine but the snapshot I have given is the invoices and I have always got my money on time. Isn't that proof enough for you!
I only received first payment. Waiting for second. (It must be received 7 days ago) I sent 2 emails but no reply... I think they are keep this money as possible. I will look for another sponsor.
