steveosh: the only problem is that i did 10 of the 11 on the same day, in a row.
I'm not familiar with your specifics here Steve, only rocky's attempts.
Have you created tickets for all the unpaid?
Do you have some kind of proof for all or most of the unpaid?
Have you emailed their customer service address with each of the ticket numbers and each individual set of proof.
I would do a single email for each ticket number, 10 emails if it were.
If all of the above is completed, then I would resend those emails each 5 days.
I resent one today for an offer i completed a few weeks ago, they have paid me on other emails sent in the meantime but one particular ticket they haven't, i resend the email every days until i get some kind of response.
Then address that response.
Usually by the 2nd or 3rd email i also CC WGT into every subsequent email.
