Thanks azaB the minimum was .99 so a nice easy one i thoiught for 250 tokens.... wont be dropping money anywhere couldve wasted way more. They asked for proof which was sent then silence...defeaning silence...
Just an update on this. Spoke to nordeus support whol followed up with offending token companies. Also completed a few quick easy challenges for small tokens knowing they wouldnt get paid. Then raised a case using a diff email address. Mysteriously tapjoy and ironsource then replied to this new email and when i asked them to review previous cases they did and apart from one challenge ive been paid all the tokens i was owed. Its almost as if the email address was blacklisted and using a new email address kicked them into gear. 1000 token balance certainly has made the team more competitive again!!
I've tried to get owed tokens off Ironsource and they just send an automated email saying I didn't provide enough proof. I sent them everything they asked for including screen grabs and email receipts. I don't use them anymore. Fyber are great at sorting out issues.
