Curiously73

I also extended mine, payment was OK, monthly card got extended but I still don't receive Kobans.

I've got the same problem, it took me more than a week to notice it but I didn't get any kobans and the banner did'nt show up. I'm not sure to be playing on Nutaku (I just log in with my mail and password) but if needed : ID is 3415342 and Nickname is Curiously73
