Just a quick update: I sent an email to Gambling Wages and within a few hours Natalie emailed me back informing me that everything is sorted out and the negative carryover will not affect my payment.
Thank you to everybody that told me to query it and also a BIG thank you to Natalie for her quick response. It is good to see that Gambling Wages (Natalie) do care about the small time affiliates. :clapper:
