You can contact Natalie at manager[at]sharkcasino.com. If you aren’t reaching her by email then maybe you’re using an incorrect email address. You might try sending an email to support[at]sharkcasino.com and put Attention Natalie/ Affiliate Manager in the subject line.
You can call her by using the toll free number for the casino and asking for Natalie. She’s usually there Monday-Friday, late morning through the afternoon. I called last week and spoke to her about affiliate payments. She told me then that she was hoping to have them done by the end of the week. I’m hoping to see my payment this week. I’m pretty confident I’ll receive my payment without a problem.
