I haven't been through your exact predicament. However I was banned from their platform a few years ago, and when I posted about it on Twitter their bitch asses blocked me on Twitter. I remember being concerned on whether or not I'd get my last payment from them (after being banned), and they DID pay me at least. I'd made a thread about it here on this forum. Now maybe they'd only paid me because they knew I'd blast them and I wasn't gonna shut up about it. IDK. It certainly isn't the first time I've had to "make a fuss" on social media in order to get paid by a company owing me money...
I'm not familiar with the Cosmo payment method, but not receiving your money 2 1/2 weeks after requesting it definitely doesn't seem right to me. I'm sorry to hear that Support isn't responding. Their Support has the reputation of not being very friendly...particularly that Linda chick. You worked for that money, and they need to send it to you and stop playing games. I hope it's resolved soon. Please keep us updated. Sorry that you're dealing with their b.s.
