The above email explains it all. My 1st Nuffnang cashout has been rejected!
So, I send them a ticket asking for clarifications and advices.
Nuffnang responded promptly which is the next day. Fast huh?!
In my case, it should be "binti" as per IC instead of "bt" that I provided to Nuffnang! *sigh*
The issue has been resolved. I will need to make another cashout since the earlier cashout earnings have been credited back into my Nuffnang account.
However, I've changed my mind. I decided to cashout later. Wanna earn more! *money eyes*
